use a font/character system similarto ASCII or Unicode?

andI donıt post the programs as separate software to

calculator as is,without anything else, and thatıs why I will
never refer to any othersoftware already available for the

ignore anything else, but that the choise ofother software is
left completely free to the readers. The usersshould be able
to get the most out of their tools without *having* tosearch
for software that they need. Do you want the prople to

is possible to use the alarm as an interrupt to another
program that is running all the time?====Well, the alarm will
Ŝrst wait for the running program to Ŝnish andit will *then*
come up. That means that the running program must checkfrom
time to time when the next alarm comes up and HALT itself and
thealarm must be a program that has CONT at its end, so that
the haltedprogram can resume.Unfortunately no HP41 behavior

This behavior is coded into the Keyeval of the System Outer
Loop ifI am remembering correctly. So the behaviour you
expect should be possible by means of SysRPL when you use
your own Keyeval. I have, several years ago, written an
almost similar, but simpler program which updates the clock
display on every second. The program puts the calculator into
light sleep, when the time update interrupt arrives, the
program is wakened, the display is updated and calculator
goes again into light sleep. That way it consumes even less
power than system time display routine. Maybe the same
approach may be used to solve your problem? I have not
published my clock program, because it uses fonts and some
and there are lot of time display programs on hpcalc.org. But
if there is interest towards it then I can send it to

everytime theseretries occurred, the packet lengths would get

reading I have found out how to correctly enter the equations
I need. With that comes a
question:X(t)=5cos(2t)Y(t)=5sin(2t)therefore:
5cos(2t)+i*5sin(2t)Why is it that we enter the equations the
way we do?====Each point on the parametric plot has the form
(X,Y). This is notjust a coordinate, but a complex number as
well. Since X and Y areeach controlled by separate equations,
it can be expanded to(Xequation, Yequation), and another way
of writing that is Xequation +i*Yequation, as you have
above.The so-called complex plane is nothing Ŝerce - itıs
just the usualXY plane with Y redeŜned as i and -i. Thatıs
how you generatefracs - each complex number out of the
equationıs iterations isplotted as a coordinate.====They
shouldnıt treat that as a complex equation. They may be doing
itthat way because it makes things easier to calculate X and
Y, by simplydoing a RE(f(t)) and IM(f(t)). The real problem
with doing it this wayis maybe you *really do* want a
parametric equation, and you input
this:x=cos(t)y=sqrt(t)t={-pi pi}On a true parametric, when
t=-1x=cos(-1)y=iBut if you treat it as complex always, when
t=-1:f(t)=cos(-1)+i*sqrt(-1) = cos(-1)+i^2 =
cos(-1)-1therefore:x= RE(f(t)) = cos(-1)-1y= IM(f(t)) = 0So
if they are automatically treating parametric as complex
(which onthe HP48, thatıs how you enter the equation - in
complex form), then (atleast by my book) thatıs not really
parametric at all! In fact, itısnot even possible to have a
discontinuity because of an imaginaryresult. They should have
probably called it complex or something,instead of parametric.
Very strange. I wish I had my HP48 usermanual to see how it
tells you to setup a parametric plot.. but itappears to want
it in f(t)+i*g(t) form. Another weird thing, if youdonıt give
it a complex part at all, you should only be able to
plotpoints right on the real axis.. which it doesnıt do.
Either Iım doingsomething wrong or itıs doing something
weird. If someone knows how theı48 expects parametric input,
could you post it?====On the parametric plots, I just
consulted my HP48 user manual and it appearsthat it does
indeed interpret everything as complex (that is the form that
youhave to enter the expressions in.. x(t)+i*y(t) ). I donıt
know why they didit this way (although I could guess that it
was to make their job easier!).Anyway, I am quite certain
that the HP49 would behave in a similar way. Mostlikely they
just made a nice, pretty front-end to the same routines the
48used.Just as a last note, I was testing those expressions
from my previous post,and the two plots look the same
(comparing the built-in plotter vs PowerPlot,which does true
parametric). But I realized that the imaginary part wasalways
0 on the build-in plotter, so you wouldnıt see any bad plot
becauseitıd be drawing over the x-axis. To see the effect I
was king about, sety(t)=sqrt(t)+1. That ŝat line at y=1
should not be there on a trueparametric plot.====What was the
problem? Itıs likely that your tangent line was caused by
aundeŜned point. If the calculator is trying to connect
points across anasymptotical discontinuity, then youıll get
this sort of effect. The reasonis often because the
discontinuity does not fall exactly on a calculatedpoint, and
therefore the program has no way of knowing it crossed
anundeŜned point.. so it goes ahead and connects the two
points, with thediscontinuity in between. This will be a
problem for any discrete databeing displayed as a continuous
function. For example, if you set yourincrement to .2 and you
are plotting Œ1/xı, what happens when -.1 is onepoint, and the
next x value is -.1+.2 = .1 ? It doesnıt see the x=0because of
the discrete step size, so it just connects (-.1,-10) to
(.1,10),which is basically drawing an asymptote. However, if
it happens to work outthat a plotted point falls at x=-.2
then the next point is x=0.. this causesan error, which on
moderately sophisticated plotter, should trap andsubsequently
skip drawing at that point, and continue to the next..
whichwould be x=.2. The result is a discontinuity. Sometimes
itıs just dumbluck. Hopefully your teacher realizes that the
machine is a tool, and nota replacement for a brain.. and
that an apt student should see some artifactand realize that
this is simply the limitation of the machine.Unfortunately,
it sounds like your teacher doesnıt realize this, and
justviews the machine as a magical box that returns an
answer, but has no ideahow the machine works beneath the
surface. Itıs like doing (2/3)*3 on acalculator, and claiming
the solution of 1.99999999999 to be incorrect. It is just as
important to understand the limitations of your tool, as it
isto understand its capabilities. I have asked this question
earlier but recieved no satisfying answers,so, how is it
possible to wire up an 48 G to print normal ascii codeto a,
lets say Canon BJ-10SX? Or any other brand that accepts
ASCIIprint out, for that er.I also have access to the HP 4L
laserjet and yes I have tried usingthe PCLPRINT - anybody
seen that work? I would love to be able toprint my strings on
a normal printer instead of using the thermalprinter...
====The 48GX and PCLPRINT with an HP LaserJet Series II works
with no problem,using the printerıs serial port. Just make
sure that the baud rate etc arethe same on both ends, and if
that doesnıt work try throwing a null modemdoohickey onto the
serial end of your cable (in case lines 2 and 3 need tobe
swapped, as the Fates decree).If your printer only has a
parallel port, a parallel-to-serial convertershould do the
trick.PS: Make sure that you have the G/GX version of
PCLPRINT! The older versiononly works on the
48S/SX.====peoples have asked me for:The Red Eye format of
the HP IR printer:To send a byte (d0-d7) to the printer you
must send through the IR led:0 0 0 1 1 1 h0 !h0 h1 !h1 h2 !h2

48GX out of storage. I was unable to Ŝnd themanual, and I had
only begun to Œget to knowı the calculator beforeneeding to
put things into storage. Iıve had a series of HPcalculators
(Dadıs 35, my own 25c, 41c, 32s & 48gx) and have a
fewquestions.1. how do I convert a number from one unit to
another? Say, Gallonsto liters?2. Is there an equivalent of
the caog of functions found on the41c?====The manual:

select the units menu and then enter inn the desired
submenuWrite the number, then press the unit key and youıll
get the number withunit in level 1.For converting, press LS
and then, the unit key.No, but this helps:

http://jamlab.home.att.net====Lets say I have the following
formula (which I do):R = ( ( P * I ) / ( 1 - ( 1 + I)^-N )how
can i get my hp49g to automagically rearrange the formula so
thatit would show the formula for solving anotehr variable (
P, I, or N)?====I would store that intoıEL.EQıthen I would
start the Numeric Solver above [ 7 ] in red.I think you can
Ŝgure out it yourself once you CHOOSıthe right
EQuation....==== (BACK UP YOUR RAM} :-)Here it is. On stack
level 2 I place ŒXı(actually any algebraic) and on level 1a
list with wonderful bad things insidelike { 1 TAN LOG } which
is by itself a simple innocent program if you hit EVAL. BUT,if
instead of EVAL you type TABVAL and ask for the values of {1
TAN LOG} out ofıXı (I know it doesnıt make sense but keepon
reading) then you DO get a list of twolists only that the
second list containsbinary garbage. I guess that the argument
checking FAILED and the machine proceededwith normal
execution. You can save this toa string and download it to
the PC to view itBUT do not do an UNDO or EDIT operation
oneither the list or the string (my machine crashed on these
attempts). Better yet, afterthat just hit a warm reset to be
sure.====I get an InsufŜcient Memory error, which is also not
correctfunctionality.====BTW, how many bugs are still hidden
in the HP49G?*If* there has been any argument checking at
all!I think that the only argument checking done,is for an
alg. object on stack level 2 and fora list on stack level 1.
Or is that not true?====Iım trying to solve 3 * 2x - 9yı *
3y^2 = 0 for yı to get yı = 2x/9y^2on my 48GX. Itıs very
simple to do on paper, but on the calculatorthe best Iıve
been able to do is either 2/9 * xy^-2 or 6x/27y^2.Those are
of course correct, but itıs driving me crazy that I canıtŜnd
the right combination of keystrokes to get it into the form I
want.Is there a way to do it (other than opening the equation
editor and justtyping it in myself)?
====6x/27y^22x/9y^2====Assuming that the vector can also
contain negative numbers and thatyou work with the HP49G. GS
is the greek S (Sigma) character 133 onthe HP49G.<< AXL IF
THEN DUP 1 << IF DUP 0 <= THEN DROP END OVER SWAP POS 0 PUT
END AXLThis will only replace the Ŝrst occurence of the
smallest positiveelement by 0. If the smallest positive
element appears more than onceand you would like to replace
all its occurences with 0, one possibleway would be to use
another DOSUBS.<< AXL IF THEN DUP 1 << IF DUP 0 <= THEN DROP
END << 1 << IF DUP minposit == THEN DROP 0 END END AXL====Can
anything else but integers appear in the vector?====Entry
points are supported for reasons.Programmers should use
ofŜcial entry points and only that.Yes using non-supported
entry points could save a few bytes, but what ismore
important: life time of an application, or around 50 bytes
saved of ato of thousands ?==== By stable unsupportedpointers
are meant the ones in the closed invervalsmore than once that
these will not move in futureROMs for the HP49. Thus, as long
as the HP49 lives, these can faithfullybe used. Not only 50
but 500 or more bytes are savedin complex applications.
Besides, the joy of SysRPLprogramming is twice as big if
using such pointers :-)====The modiŜed extable has several
different purposes.1. It greatly improves the readability of
decompiled code. A lot of pointers, and in particular RAM
addresses are now displayed by name.2. Programmer who wish
can easily use the unsupported-but-stable pointers. However,
we mark all those entries with a Ŝnal underscore (like
RunInNewContext_), to make users aware they are using
unsupported pointers.I personally use UBS pointers mainly
when it is difŜcult to see howto achieve the same
functionality with supported pointers.But I agree with
Wolfgang, that the programs are being written for theHP49G
now, and the reasons to worry about compatibility with
futuredevices are very limited.- It seems to be highly
unlikely that another high-level calculator will be released
by HP *and* still use the same operating system as the
HP48/49. Also the screen/memory/hardware will be different,
and all features of current programs which make things nicely
Ŝtting into the screen/memory... will be obsolete. Everything
will have to be rewritten anyway. Even most HP48 programs
required signiŜcan attention before they run on the 49G.-
Future devices will very likely use different programming
languages.- The only real worry is that when the HP49 OS
source code really becomes public domain (I still have to see
it before I believe it...), people might create new ROM
releases and ignore JYAıs promise to keep the stable regions.
Naah, they have just release new models, which have a real
keyboardfaster Saturn-CPU and the USB pointers have
changed!!! [to use unsupported but stable entry points]Mika
Heiskanen and even Bill Wickes used them extensively,
however,in some of their own published additional HP48
software [e.g. Jazz]Of course, the stability is much easier
to guaranteefor discontinued models which have no ŝash ROM
:)Read my lips -- no new taxes! [G.H.W.Bush :]Can they be
promised to move no more than a few nibbles, then? ;-)The
only serious problem is that WR is torn between the Deviland
the Deep Blue Sea, eternally condemned not to achievethe
absolute minimum possible number of program bytes,thus
destroying their perfect beauty. 7203====The other day I went
through the programs Iıve got in the LIB, now mycalc doesnıt
want to display these kind of fractions anymore1-2It will
always display .5, and sometimes even use the E-whatever
afterthe number.I donıt like it. Which ŝag did I set? or is
it some program running.====Hi,your calc is in approximate
mode. Just type ŒCASCFGı and press Enter.Roman====CASCFG does
a lot more than just set Exact mode, so Iıd recommend
avoidingit except when really needed.My favorite solution to
the unwanted Approx mode prolem is to type XQ.This would
convert your .5 into 1/2 *and* change the HP49G to Exact
mode,all in one swell foop. The reverse operation, by the
way, is XNUM. Theseonly work if thereıs something on the
stack.If you have a recent enough ROM version, you can easily
toggle Exact/Approxmode by pressing the ENTER key while
holding down the right-shift key; watchthe annunciators in
the top line and see = (Exact mode) or ~ (Approx mode).In any
ROM version, you can also press MODE CAS and then check or
uncheckApprox.You can programmatically turn on Exact mode by
-105 CF, and turn on Approxmode by -105 SF.Hope this
helps!-Joe-====I prefer having the Vectored ENTER ŝag on (as

today: an old Casio fx 4000P that Iıve bought for 6? inebay
last week.Just nostalgia. It was one of the most desired
calculators among myclassmates while we were studing
Chemistry in the middle of the 80ıs: oneof the Ŝrst
affordable alphanumeric calculators, and one of the Ŝrst
purealgebraic, where you can write normal: sin 30, ln 2, etc.
And best of all,550 prg steps!I have been playing and
programming it, now, comparing it with the 15C(1982).The
Casio is quicker: calculating P100,50 takes more than 7
seconds in thehp but itıs almost instantaneus in the casio.
Its alphanumeric screen isbeatiful. Its statistical
capabilities are better ( I need a program forentering 1 var
or 2 var with freq in the hp)... and nothing elseThe hp is
solid and durable. The keyboard is much better (not as those
casiovery little keys). Itıs humble segment screen is big and
easy readable. Andthe matrix operations, a blessing.BUT above
all, RPN is much efŜcient than the algebraic system: is
veryboring pressing ANS all the time and most of prgs are
30-50% shorter in RPN.As Jean Lemire has posted, RPN is THE
way.====Almost instantaneous on the TI-89 as well (less than
0.1 second).--====Sean,I was very much like you for a long
time in that I couldnıt Œgetı RPN. I justcouldnıt Ŝgure out
how to think in RPN mode.I guess Iıve had my HP49G for two
years (Ŝrst RPN calc for me) and I stillconsider myself a
newbie, but about 6 months ago, and after visiting
thisnewsgroup almost daily, something suddenly clicked and I
havenıt gone back. Istill think RPN is difŜcult to read but
its very easy to calculate in RPN. Idonıt know about you, but
I have a little voice in my head whenever I
performcalculations, either with paper or with a calculator.
When it Ŝnally clicked,it was because I realized that I
Œthinkı in RPN mode. Haha.Anyway, some very useful keys on
the HP49G while working in RPN are ŒENTERıwhich duplicates
the last entry on the stack (DUP command), and the
rightarrow, which swaps the last two entries on the stack
(SWAP command).Thereıs one last thing; when all else fails
and you need to enter something asyou read it while in RPN
mode, just put it within single quotes. Simple enough.Hope
this helps,- Ian====theAs on the hp48.====We should now go
back to number crunchingand feed a 16x16 numerical matrix to

from. the fact that themultiplier between the core and the

crappy new cache? or something more subtle?

prone to heavy thrashing when memory datais not spatially
close, whereas other ARM implementations seem tohandle this
much better. For instance, a pixel dissolving algorithmthan

Dimitry.Br.9fder-Peter====HiThe present version at hpcalc is
too old.Longŝoat has been updated to version 2.5 and this
version will be uploadedto hpcalc today.It is now possible to
have automatic evaluation of algebraics and matrix
ofalgebraics for most functions to arbitrary precision.User
deŜned functions in sub expressions are allowed. However,
these shouldnormally return longŝoat numbers.E.g.50 DIGITSı
STO1.25 ŒXı STOıSIN(Z*pi*X)ıevaluates automatically to 50
digitsAlso, a *single* matrix expression from CAS can be
numerically evaluated toarbitrary precision, but use the CAS
Ŝrst to simplify :[[ŒSIN(2*X)ı ŒSIN(X)ı ]] ŒY1ı
STO[[ŒCOS(2*X)ı][ŒCOS(X)ı]] ŒY2ı STOıY1*Y2ı ( not allowable
simplify Ŝrst)EVALand you have evaluated y1*y2 to
approximately 50 digits ;-)Note: Although each single
function ( e.g. SIN) is evaluated to a precisionof +/- 1 in
last digit, the resulting precision for e.g.
ŒSIN(X)*COS(X)*piıwould generally have less precision.And for
single algebraics Thoması unitfunctions are included
;-))Gjermund Skailand====I guess there is no precision
tracking?--====There has to be, for it to be useful...====One
could do the algorithm analysis on a PCand then change the
internal calculation accuracy of each algorithmto reŝect the
needed output accuracy.Ofcourse there are cases where certain
input ranges require specialattentionand one much either
switch to a different algorithm or change the
internalaccuracy based on the input value (or exponent).Just
some thoughts.====HiWhen I was in military we had a simple
rule: if it you didnıt use enougheplosive the Ŝst time then
you double and try again.i.eYou would have to repeat the
calculation with more digits and compare theresult.but
seriouslyhow would you do presision tracking even on
something as simple asa-b where a is almost equal to

doesnt work for allproblems...considering that u have to
worry about order of operation.FURTHERMORE...i Ŝnd it tedious
when it comes to simple problems suchas 6+5*6-6/7. The TI
automatically takes care of order of operationsfor me. With

interwoven...It takes a little getting used to. When I Ŝrst
got a HP49 (which isvery nice btw), I thought most people in
this newsgroup were nuts forliking such an arcane thing as
RPN. Why complicate things? After a dayof playing with the
thing, It really seems alot easier to me. It justtakes
practice. Of course, some people will never like
RPN...Perhaps you are thinking about it the wrong way. Hereıs
how I thinkabout it. With algerbraic, you basically type the
thing in as you seeit and boom, the anwser appears. With RPN,
you Œbuildı the equationstep by step. EG for 5+6+7+8, I
think:get 5. add 6, then add 7, then add 8 - which translates
to5 enter 6 + 7+ 8 +Not much of an advantage so far Iıd
admit.IDo it like you would by hand - multiply 5 by 6, then
add 6. work out 6/ 7 then subtract.5 e 6 * 6 + 6 e 7 /
-Again, no point for something like this.Hereıs a trickier
problem. Solve:5^(sqr(7*4^Pi))/(8*9/4+sqr(7^2+5^2)) (30
keystrokes)It would take me several tries to get that right
via algerbraic. Putthe brackets in the wrong spot and you get
the wrong answer. Thebeauty of RPN here is that as you build
the equation, mistakes arevery easier to spot and
correct.EG:Take 5. Work out 4 to the power of Pi. multiply
that by 7. Sqr theresult. Put the result as 5ıs power. etc.
etc. etc.5 e 4 e Pi ^ * sqr ^ 8 e 9 * 4 / 7 sq 5 sq + sqr + /
(23 keystrokes)Looks hard like this, but when you have a
screen in front of you it;seasy. Saving almost a third of
keystrokes is a bonus.both a blessing and a curse.To be
honest I don;t know what the delimeter button is... You
meanthose tick things?Donıt think of RPN as a painful chore
brought to you by the old schoolelite (like I used to ;-) but
rather as building an equation step bystep. The biggest time
saver is not having to correct your equationafter mismatching
brackets. Fewer keystrokes as well.Hope this
helps,Alwww.alborowski.tk====Erm, but what about (5+6)*(3+4)?
Algebraic systems deal with theprecedence of operations for
you when it agrees with the predeŜnedprecedences, and only
then.--tim====Hi,I Ŝrst learned RPN on my HP-45 in 1974 and
to me it was THE way togo. In fact it is like I learned in
school.For example if you want to add 734 and 136 what I
learned was to put734, then under it, 136, then add like:
734+ 136------ 870With RPN :734 ENTER 136 +The fun with RPN
and a multi line display is that the stack shows thenumber as
you would put them on paper to perform the operation byhand.As
for the examples given by others work them the way it was
explainedin HP instruction books of that era (1970ıs).Type a
number.Can you perform a monadic function on it (monadic
means using only oneargument, like SIN, SQRT, LOG, etc.). If
yes, then do it. If no thenpress ENTER to push the number on
the stack.Type another number.Can you perform a dyadic
function (function with two arguments)withthe one already on
the stack and the one you have just typed. If yes,then do it,
if no then press ENTER to push the number on the stack. With
HP 48, 49 and the like, you can see the Ŝrst few levels of
thestack and keep an eye on what is going on. With older
models like 45,function to manipulate the stack and check
intermediate values.So, for a more complex example like:e^3 +
7 / (4 + 5 / 6)You can type:3 e^x 7 ENTER 4 ENTER 5 ENTER 6 /
+ / +For a total of 13 keystrokes.Of course you can perform
this calculation from the deepest levellike:5 ENTER 6 / 4 +
1/X 7 * 3 e^x +for 12 keystrokes. Not a big saving.Or:7 ENTER
5 ENTER 6 / 4 + / 3 e^x +Again 12 keystrokes.Hoping that helps
a little.Jean Lemire from Montreal.====supposed to just typing
in the numbers and getting a meaninglessanswer with the
TI...but iıll have to spend some time getting used

hp49g. I try a sys-rpl program today(apart of MoonLight), and
now is my hp49 not working. I see only theTry to recover
memory screen, and I can do anything. The yes[F1]-key and the
no [F6]-key doensnıt work, and when I try to usethe [ON]-key
the calculator make a continuous bip.I try all: [ON][C],
[ON][F1][F6], [ON][F3][backspace], RESET on theback of the
calculator, take out the battery, NOTHING!!Itıs terrible. I
donıt kwon what I should do.Please if someone know how to Ŝx
this problem, help me.Dimitri.====I am just reposting a Ŝx
someone else posted about a similar problem,try what is
suggested below, hope it works.Stan.---------try to reboot
with [ON]&[F4] - Q and press while rebooting
thebackspace-key(The broken lib wonıt be attached this way).
If the library is causingtheproblems this should solve it.
Donıt forget to purge the broken libwith theŜler.BTW: The
program P0erase ist just to be used if the
upgrade-processgoeswrong and you donıt even have acces to the
download menu anymore.Hope this
helpsRoman----------towithtakesonwhenONkeyboardjustyet====hi,
Did you try to reboot with [ON]+[F4],[Q]+[BACKSPACE]? The
right timing ofpressing the backspace is important.If you
still should have acces to diagnostic mode ([ON]+[F4]) you
can try toreinstall the OS. I assume you have the
connectivity kit.If this still doesnt work you can manually
format your ŝash-rom (port 2). Ihad to do this once to make
my calc work again.There is also a program at www.hpcalc.org
you could try. The name of theprogram is P0erase.Hope this
helpsGood luckRoman====I just remembered that he program
P0erase makes only sense in case yourupgrade process went
wrong and you donıt have acces to the download
menuanymore.The other post above helped me to remember about
some other post coveringsimilar problems with hp49g in
unusable states.Here is a more detailed guide to bring your
calc back to life. Most of thisthings mentioned you have
allready tried. But as an example pressing thebackspace at
the exactly right time while rebooting the calc is not
thateasy but important, so you have to try maybe a few times
till it works.(make sure youıre using new batteries before
trying this!!)1) Press [ON]&[F3] to reboot the calc and while
rebooting the backspace key(try this several times as the
right timing to press the backspace key isimportant)if it
fails ...2) Reset your calc with a paperclip (there is a hole
on the back of thecalc)if it fails ...3) try to reset with
[ON]&[F4] -Q and press the backspace-key whilerebooting (this
way an eventually broken lib wonıt be attached, Donıtforgetto
delete the broken libs)if it fails ...4) Reset your calc with
[ON]&[F1]&[F6]if it fails ...5) Download the OS againif it
fails ...6) If you donıt have acces to the download menu
anymore use P0erase (makesonly sense if your upgrade process
failed before)7) Install the OS againif it fails ...8) Erase
bank 8-15 (Port 2) manually, do this in the download-menu.if
it fails ...9) Take the batteries out for some daysif it
fails ...you have now a very cool paperweight ;-)If the unit
is still under warranty get a replacement.Roman====When you
press YES it may take quite a while (Iıve seen cases with
30minutes).If you donıt want to wait, simply press NO, but
you will loose all yourdata.Otherwise, Press [ON] and [F3] at
the same time.If it fails again, then try pressing [ON]-[F3]
and just when you releasethese two keys, press and hold the
backspace key until you see the homescreen.Then using the
Ŝler delete the corrupted object.If you do not get anything
happening with your calculator, then using apaperclip press
the reset button in the back of the calculator for about
5s.Then press the ON key and see what happens..Forget what
youıve read in other messages like using P0ERASE this has to
beused ONLY when the upgrade from rom 1.19-4 (and before) to
1.19-5 or 1.19-6fails.In your case I doubt reŝashing the
calculator will be of any help as Iıvenever seen a SysRPL
program damaging the ŝash.Just pressing the right key will
make it work for you====I try all possible. The problem with
my hp49g is: I canıt use any key,I canıt access any
diagnostic mode, I also canıt reboot, and I canıtaccess
download menu. I canıt use any combination with [ON]. I
justsee the try to recover memory screen when I click [ON],
and the onlykey that responds is the [ON]-key with a
continuously bip bip bip... as long as I press [ON]. I just
see the small sablier, sandglass(that show that the
calculator is doing something). I triedalready to reset the
HP49G on the back of the calculator(I thing morethan 50
times).I try to remove the battery for more thant 12
hours(itıs was a tip ofthe [ON]-key for more than 5 mn(Also a
tip from Prof. WolfgangRautenberg), but I get nothing, only
this bip.I really donıt know what I should do. Itıs terrible
that only becauseof a software problem Iım not more able to
use my hp.I hope I will Ŝx this problem(with any means
necessary).I donıt want to use my hp as a very cool
paperweight(I read thisjoke in one of the answer). I am not

bzDIR andaccidentally pressed ON during the operation. The
calculator wentdead, and I had to use the hardware reset to
get the HOME screen toappear. No keys worked except
ON-combinations. I tried ON-A-F andgot TTRM, but it ignored
Yes and No. I tried rebooting with thebackspace pressed and
it made no difference.So I ran the ON-D diags and it said
that there was a CRC failure inBank 1. I reŝashed the ROM and
everything is now Ŝne. Includingthe SysRPL version of bzDIR
that seemed to cause it.Bill====Hi Thomas!Astonishment! This

both primes. Is that false?Greetings,Nick.====Seen:This
provides a shorter proof, at last, of Fermatıs Last Theorem
:)Something similar is commonly used, however,to conclude
that some integer is prime,which the HP49 will sometimes
assert when it isnıt so,because the abbreviated procedure
only indicates a probable prime,much as you can get arrested
for only a probable crime :)I believe that RSA public key
generation also commonly tests forprimes in only a
probabilistic fashion, based on the extremely lowprobability
of generating a bad key pair (itıs possible thata bad pair
wonıt actually work in practice, though,which if so would
constitute a Ŝnal positive test).More examples of highly

prime-generating n for some poly pairs is very large (in

there arenıt any. Iıve yet tosee a Ŝrst n greater than 1E6,
but methinks thatıs only because I havenıtlooked long enough.
But... thatıs just a feeling, and Iıd equally enjoyseeing it
proved or disproved.-Joe-====However... You proved that this
particular poly pair is prime-pairoutput-free by examining
inputs mod 6. Some other poly pair might be a mod12
situation, right? Or mod 210. Is there any way of reaching
our goalwithout using trial and error on sets of inputs mod
m? Or is there any wayof determining what the modulus is
without trial and error?-Joe-====Yes, I read about it a while
back. Itıs pretty decent work ;-)====This new algorithm is not
*fast*. It runs in polynomial time and providesa deterministic
answer about the primality of a given number. There
werealready other such polynomial-time algorithms, but those
didnıt work for*any* number (only special cases ones).In
crypto, we use good sub-exponential probabilistic
non-primality tests(such as Fermat, or Rabin-Miller), which,
when run enough times, providea good primality test with a
deŜnable risk of being wrong.Theoritically speaking, the
algorithm youıre talking about is a greatenhancement, it
proves that the primality test is a P-class
problem.Unfortunately, the proposed algorithm runs in O((log
n)^12), where nis the number to test. This is too slow to be
practical. In practice, itcanıt compete with a good
Rabin-Miller that runs in time O((log n)^5). TheRabin-Miller
must be run a number of times to minimize the risks oŝetting
a composite pass the test, but this number of times is a
small one(5 or 6), and it decreases when n grows.-- -----AD:

sequence0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,
7,8,9,0,1,2,... ?Isnıt that a totally uniform
distribution?Or, do you mean that if, out of a 100,000 digit
sequence,there were *exactly* 10,000 of each digit? That
would betotally uniform, but highly improbable, would it
not?It can be a tricky subject unless one is really
clearabout what one really means, and also not
continuallychanging the meaning, perhaps without even
realizing it,producing apparent contradiction.One framework
in which to put it is in terms of knowledge.You know the
past, but not the future; actually, this canbe turned around,
to say that what you know and what youdonıt know are what
deŜne the realms of past and future,and that time is the
successive unfoldment of knowledge.The degree of randomness
is then the degree of yournot being able to know. If you have
seen the next pagein the Rand Corpıs list of digits (was that
Herman Kahnmentioned in the list of references?), then you
knowsome information, while someone else who has not seenmay
not know, and if there exists no signiŜcantly simplerpattern
for predicting the unknown digits than the digitsthemselves,
then that deŜnes their condition of beinga random sequence,
from the perspective of one whomight yet not know the
sequence.Inability to Ŝnd a pattern does not demonstratethe
non-existence of a pattern; a battery of common testsdoes,
however, often detect simpler patterns, and thuscan
demonstrate lack of randomness.A good pseudo-random number
generator or good cryptographyshould minimize the
detectability of such patterns;it is a challenge to generate
longer streams of outputthan the saved system state without
making such patternsdetectable, and affording knowledge of
the rest of the unknownfrom a smaller sample of the
known.What we call science generally has an exactly related
aim,to know much more (and to be able to predict or cause
effects),from as little an original collection of the
known(and also, importantly, with least effort) as is
possible.So it all comes down to our state of knowledge vs.
ignorance;should it ever turn out, in our own personal
experience,that we can have a state of consciousness that is
simultaneouslyone of absolute simplicity and yet all-knowing,
one in whichthought organizes its own accomplishment, with
least effort,and which every conscious person can have, then
we will havea supreme science, a Science of Creative
Intelligence.Some theory

such an example I wanted to use today for telling
randomnessBut seriously, according to the strict mathematical
deŜnition isnıtthat a random sequence? You can of course
predict what comes next,but only because you *already have
seen* the sequence itself, and haveobserved the underlying
pattern. This confuses me a little bit. Whatis this (or any
other) sequence?1) Is it the result of already having
randomly picked numbers out of apool 0-9 that contains all
numbers from 0 to 9 equally often? If so,could you predict
that this very sequence will be formed if you pick30 (or what
so ever) numbers out off the pool? I believe not. If
thesequence represents the outcoming of some experiment that
we didnıt doyet, then you and me and anybody else couldnıt
predict what numberwould appear next, or am I wrong here? The
sequence is then one of thepossible outcomes of picking
randomly numbers out of a pool which ismade in such a way,
that all numbers are equally likely to be pickedout. The
special case 0,1,2,3... isnıt special at all, it
appearsappealing to us because it is something that we
recognize easily. Butany other sequence would be exactly as
probable before we make theexperiment.2) Or is the sequence
itself the pool which I should pick numbersfrom? Though this
is not the strict mathematical deŜnition, if weaccept it,
then what comes next becomes predictable, *if* we knowwhich
position of the sequence we are at.The mathematical deŜnition
of a random number is just that, if youpick a number out of
some pool (i.e. distribiution) then all numbersare equally
likely to be picked out. So a sufŜcient large number ofpicked
numbers reproduces the distribution from which the numbers
werepicked. If you have a pool of integers from 0 to 9 and
each of theseintegers is available the same number of times
in the pool, thenpicking randomly 10 numbers from the pool
can make the sequence0,1,2,3,4,5,6,7,8,9 of *picked up*
numbers, exactly like it couldcreate 3,4,9,0,1,6,2,5,7,8. And
here is where I have my difŜculties.The so created sequence is
unpredictable *until I see it*. After Ihave seen it, of course
I can Ŝnd always someformula/algorithm/whatsoever that
reproduces this sequence. But for methis doesnıt make the
randomly created sequence less random, becausethe next time,
when I create another random sequence using the samepool and
the same procedure of picking, I still canıt say what
comesnext.I canıt understand what you mean here, John. Can
you elaborate?Exactly. But here I have two possibilities. Is
the sequence the past,i.e. is it already created when I
justify if it is random or not? Ordoes it yet have to be
created by picking numbers? If I forget for amoment the math
deŜnition of random, then what sequence can berandom at all,
when there is always a way to reproduce an alreadycreated
sequence by some formula? I think that this is why
therandomness is deŜned as it is deŜned mathematically. If we
couplerandomness directly to unpredictability, then weıll face
difŜculties.Pattern recognition is always possible on a
*known* sequence ofnumbers, events or anything else. The
problem is to predict whatpattern the next test (of the same
kind) will produce. But speakingabout patterns, perhaps we
humans have the ability to regognize toomuch patterns, or
even to recognize patterns there are none. (Example:Husband
recognizes pattern: When wife comes smiling to me, she
wantsme to do something for her ;-))This introduces an
additional concept, mapping. A known cypheredmessage,
received as a sequence of bytes for example, can
bereproduced, in the sence that you can create exactly the
same sequenceof bytes, by using some algorithm. But you canıt
map this sequenceonto another, so that the human readable
message is created. And thefact that some given algorithm
creates this cyphred sequence of bytesof course doesnıt help
us for the next message.But letıs stay on simpler things for
the start, just random sequencesof numbers.Predictability is
not the same like randomness. When we examine somenature
phenomenon, then we could say that we just pick some
valuesout of a pool of such values. But the pool doesnıt have
an uniformdistribution of these values over the range of
possible values. Someof them are strongly prefered, while
most of the others are almostneglected. The pattern for this
is just what we call law ofnature, isnıt it? We make a Ŝnite
number of experiments, start tosmell that there is a pattern,
and the we Ŝnd something likeF=dp/dt which explains why some
of the possible values for, say F, areso strongly prefered.
But if we have a totally uniform distribution,then *before*
we pick the numbers, we canıt say what will be pickednext. Of
course after picking them, we can always construct someformula
that constructs exactly the same sequence, like that which
wejust created. But the next time we pick numbers again out
of theuniform distribution, to make a new sequence, we will
Ŝnd somethingcompletely different, because the distribution
is uniform. So havingan already constructed and known
sequence, doesnıt make it un-randomjust because we can
reproduce it.It appears to me that you must be way ahead of
me, since I canıtunderstand a single word of what you say
here. But please, even if Iam too stupid to realize what high
meanings these words could have,allow me to enjoy my journey
to that state of consiousness (if itexists), let me be slow
and donıt put me in a hurry, OK? Let meexamine each and every
single stone on the way, wherever this waymight take me. And
even if I miss the high target that you alreadyreached and
land at the cottage of Trabakoulas, it doesnıt matter.
Thejourney is enough for me.And I have my own options, maybe
wrong options, but even if I ammistaken in these options,
hey! they are *my* mistakes. This is me.Even more best wishes
from just the mistaken me.Nick.====Hi Veli-Pekka!Considering
randomness you should predict not what digit comes in
an*already* constructed sequence of digits, but what the next
digit willbe if the sequence is just being made. It is what
digit you will picknext (with closed eyes) out of a bucket of
digits, in order to makethe sequence. If you canıt say what
digit you will pick next, then theso constructed sequence is
a random sequence, no matter if you cansomehow reproduce it
after you Ŝnished picking numbers. It is the wayyou
constructed the sequence that makes it random, not the fact
thatyou can predict its digits when it is ready.Predictable
greetings,Nick.====whatissues.More troublesome than difŜcult
philosophical issues are difŜcultphilosophers, of whom we
constitute two. ;-)PHILOSOPHICALLY, an event is truly random
if and only if it is unbiased*AND* unpredictable *AND*
unreproducible. However, every *speciŜc* numberlacks all
three of those qualities, and hence is thrice
non-random.Non-randomly picked example: 17. 17 is biased; it
*insists* on being 17.Itıs predictable; itıs *always* equal
to 17. And itıs reproduceable: 17 1717 17 71 (oops) 17 17 17
... as many as you want.Replace 17 above with any other
number and the paragraph remains true.Therefore all numbers
are intrinsically non-random when taken alone, Q.E.D,+/-
3dB.NUMERICALLY, a numeric sequence is sufŜciently random if
it passes TestSuite X chosen by Person Y for purpose Z, where
X and Y and Z areunpredictable but highly biased and
reproducible. Thatıs so subjective thatit boils down to, Itıs
random if you think itıs random, leading me tosuspect that
numeric randomness is an art, not a science.-Joe-Free online

NumberTheory?discipline=Mathematics==== Isnıt this called
begging the question? You select an admittedly non-random
numberand then proceed to show that it doesnıt have
randomness properties. As I said in an earlier post, what
makes a number random is not some intrinsicproperty, but
rather the process by which it is selected. Kosher meatıs
koshernessisnıt intrinsic; itıs a certain process that makes
it kosher. The numbers in a sequenceare only random if they
are selected by a random process, and the sequence will
likelyhave certain properties and lack certain others. If the
sequence is large, we can applytests to Ŝnd out if it is
likely to have been generated by a random process. As
thesequence becomes smaller, these tests donıt work well. But
this doesnıt change the factthat the sequence is random
(meaning that it was generated by a random process). It
onlymeans that we cannot show a posteriori that itıs random.
But we can know it by knowinghow it was generated. If we have
a large sequence that all agree is random, and select a very
small subset,does that subset lose its randomness? I think
not; itıs just that taken in isolation andwithout knowledge
about how it was created, the usual tests cannot tell us
whether it islikely to have been created by a random process,
because it is very small. But if I knowthat it was created by
a random process because I did the creating, then I can know
thatit is a random sequence. A thing may have a quality which
is not discernible from the thing itself. The powercompanies
are starting to sell electricity which has been generated by
greentechnologies such as windmills. We canıt tell from the
electricity itself if it has beengenerated by a green
technology, but it it has, then it IS green and we call
itgreen (we humans DO like to name things, and then argue
about what the names mean). Wecannot know of this quality by
examining the electricity; we have to know that itısgreen by
knowing how it was generated. So with small random sequences.
Therefore I assert that all numbers are not necessarily
non-random when taken alone. Itake an agnostic position;
given an isolated number and with no other information,
thenumber might be random (selected by a random process) and
it might not be. I cannot know.However, it is only I who
cannot know. The (mathematically literate) person who
selectedthe number knows and they could tell me; then I would
know. But given a large sequence ofnumbers, there are tests I
can apply which can indicate whether the sequence was
generatedby a random process. Sequences which are generated
by pseudo-random generators are completely
deterministic,non-random, and yet they can pass all the tests
designed to show randomness and are usefulfor the purposes to
which random numbers are put, even though they are not truly
random.Perhaps to be precise, we should say that the tests
donıt so much tell me if the sequencewas generated by a
random process, as they tell me if it was generated by a
non-randomprocess. They can falsify the hypothesis that the
sequence is random. Q.E.D.====No! *I* havenıt got the balls!
... Um, whatıs that? ... Oh, *so* sorry.Unfortunate choice of
words. Ahem. What I mean is, the winning numbers arenot random
in and of themselves, because if they were, they could just
usethe same numbers every time, because theyıre random, and
thatıs all we need,right? No, of course not. The *sequence*
of winning numbers is generatedby a *random process*, and as
long as that process stays random, it producesa random
sequence from which winning numbers are *sequentially*
chosen.Itıs not the numbers that have the property of
randomness; itıs thesequence, because of the process that
generated it.Causality. Essential concept. Without it, we can
only have sufŜcientlypseudo-random, but not random.If that
were correct, that each number in the current winnerıs list
is arandom number, we could therefore reuse those exact same
numbers(pre-determined to be truly random numbers) for each
lottery! No need forthat machine any more! Of course, after a
few lotteries, everybody wouldnotice how the same random
numbers keep appearing, and everybody would beton those, and
everybody would win!No. Itıs the *sequence* of winning
numbers thatıs random, not any of thenumbers themselves.Is
sequence S random? Maybe. Depends on how it was generated.Is
number X random? No. Is 6 a random number? Is Giovanni H.
Jonesmythe arandom person? If you say, That depends on the
sequence from which youextracted that example, then I rest my
case. Itıs the *sequence* thatısrandom, not the elements
therein, just as the set of primes is an inŜniteset, but none
of the primes themselves are inŜnite. Randomness is aproperty
of *sequences*, not of numbers, and sequences *inherit*
thatproperty from the process that creates them. No, the
elements do notinherit the properties of the sequence, as
shown already with the case ofprime numbers, and just about
every other integer sequence in Sloaneısdelightful

could argue? Itıs not just arguable; itıs an historical fact.
Printall the winning numbers ever picked, and what do you
have? Yes, quite. Asequence. A *random* sequence, if the
machine uses a physically randomprocess to create that
sequence.Au contraire! Itıs not only relevant, itıs essential
to the discussion!The randomness of a sequence *depends* on
the process that created thesequence, doesnıt it? Where else
would this quality of randomness comefrom? Do we *impose* it
upon unsuspecting numbers regardless of theirorigin and
without their consent? Is it not rather *caused* by the
processthat generated the sequence?It all depends on this: Do
I believe that mathematics is a useful butimperfect
abstraction from external physical reality, or do I believe
thatso-called external reality is merely an imperfect shadow
(cast on the cavewall of my consciousness) of imponderable,
ineffable, mathematically purerealities? In brief, am I a
Realist (aka scientist) or an Idealist (akaPlatonist)? And am
I such by my own free will, or was it determined bythe Fates?

thing to boggle.====Ok, letıs start from the top.Is 3 a
random digit?-Joe-====That is correct, since all numbers are
actually of inŜnite length (in showall leading and trailing
zeros mode). No paradox, just reality.No, it doesnıt mean
that, and hereıs why. I can write down the number
0.153exactly. But thatıs because 0.153 is not a random
number! I picked it onpurpose, not randomly! If I were to
create a TRUE random decimal-numbergenerator, it would NEVER
pick 0.153! Thatıs what probability theory says,anyway: the
probability of an event is equal to the number of
successfuloutcomes divided by the total number of possible
outcomes. There is onlyone decimal number equal to 0.153, and
there are inŜnitely many possibledecimal numbers (or MORE than
inŜnitely many, if Hilbert was right). SoP(0.153) = 1/inŜnity
= zero.The only alternative I can think of is to reject the
notion that 1/inŜnity= zero, and go instead with the much
more palatable notion that 1/inŜnity =inŜnitesimal. Would you
be comfortable with the statement, Theprobability of a random
decimal being 0.153 is inŜnitesimal? I hope not,because
1/inŜnitesimal = inŜnity implies that 1/0 must be *more*
thaninŜnity, which makes no sense, so division by zero must
remain undeŜned,which throws most of the calculus into the
ash can, because it *depends* onthe concept of deŜning
division by zero for patching the holes indiscontinuous
functions. Hence, by reductio ad absurdum, I reject
thealternative, and stick with the common notion that 0 and
inŜnity arereciprocals.This whole discussion reminds me of my
studentsı refusal to accept that0.99999... is *exactly equal*
to 1. Not merely approaching it as a limit;*equal* to it.
Counterintuitive to the max, but mathematically
certain.Exactly. The probability of a rational number being
generated by a trulyrandom number generator is zero, unlike
all HP pseudo-random numbergenerators which ONLY produce
rational numbers. I wanted to mention that inthe original
posting, but I thought to myself, Nah, leave it out;
somebodywill probably disagree with it, even though itıs
mathematically certain.-Joe-====Itıs related to the concept
of inŜnity, which I also found really hard tograsp at Ŝrst. I
hope you wasnıt hard on him or her? ;-)Only time and thought -
not lessons - will let the student see the truth...==== So we
can write down some numbers. I picked it on ^Cantor^ was
right). So But by this argument, we can never write down a
random number since every other numberbesides 0.153 has the
same probability of being picked, namely P(random
n)=1/inŜnity. ====Ooh, you caught me red handed! Youıre
right; 17 is in fact one of thewell-known non-random numbers,
and I knew that going in. How very uncouthof me. Please let me
know which random number youıd like me to use nexttime.
;-)intrinsicIs that another way of saying, Numbers arenıt
random, but processes ofselecting them can be? If so, then we
agree.Aha! As I understand it, a rabbiıs blessing creates a
*relationship*between the food and God, and itıs that
*relationship* which makes itkosher. Is that correct? If so,
I see what you mean: X (some person orplace or thing or
number or other concept) can really have a relation ofsome
kind with Y, and that relationship is a real, actual quality
of X, butit cannot be *detected* by any kind of examination
of X alone. [Forexample, I own this HP32SII. There is a real
relationship of ownershipthere; it *really is* mine. But
there is no way that anybody could discernthat fact by
examining it, since that relationship has not caused any
uniquephysical changes to it.] Only by oneıs *knowledge*
(thanks, JHM!) of X andY can their relationship be
known.Similarly, if a single number or Ŝnite sequence of
numbers is extractedfrom an inŜnite random sequence, the
randomness of the sequence might notbe detectable in the
Ŝnite sequence, and is certainly not detectable in thesingle
number, BUT the fact remains that there is a real
relationshipbetween the random sequence and the Ŝnite
sequence... and even the singlenumber!Methinks there is a
convergence of ideas happening here. I *love* it whenthat
happens!-Joe-====Rats. I picked a random mathematician and it
was the wrong one. Phooey.Hilbert *is* a random mathematician,
right? Or *was* until 1943, when hebecame terribly
ill-conditioned for any kind of mathematics other
thandecomposition.Correct. Give me a counterexample, and Iıll

and you tell me thatıs the number, boy!,then of course it is
not random. But this is not the question. Thequestion is, how
was this 3, as a sequence iof only one digit, wasconstructed.
If you tell me to close my eyes, and just pick a numberout of
a bucket full of 1ıs, 2ıs ... and so on, and if it just
happensthat I pick this 3, then this 3 *is* a random sequence
of only 1number, not because I donıt know now what number I
have in my hands,but because I couldnıt tell that before I
picked it up. The way thesequence was constructed is
imposrtant, not if we can somehowre-construct it after we
already have it.Iıll answer to you with another question. As
John asked, is0,1,2,3,4,5,6,7,8,9 a random sequence? Be
careful here, because if yousay no, then I have to ask you if
you think that this sequence isimpossible to create with the
random number generator of the HP49G.And if you think that it
is really impossible, then consider thesequence
7,2,5,9,1,6,3,8,4,0. Is this more or less possible?In fact
they are both exactly as possible, the only difference
beingthat on the Ŝrst we all readily recognize a pattern,
while on thesecond.., well it is harder.BTW, there is no
single Ŝnite sequence on this world, that canıt bepatternized
*after* it has been constructed. To use the same exampleas
above, enter [[1 2 3 4 5 6 7 8 9][7 2 5 9 1 6 3 8 4 0 ]] and
press[LAGRANGE] on the HP49G. You get a polynomial that
predicts alldigits, that is if X=1, then it spits out the
digit 7, if X=2 then itspits out the digit 2, and so on, X
being the ordinal number of thethe digit in the sequence. You
can do that with each an everysequence, after you have
randomly constructed it. Does this mean thatyour hands obeyed
the law of the Lagrange polynomial when theypicked the numbers
out of the bucket? Of course no. The importantthing is how the
sequence was created, not if you can re-construct itlater on
using some rule. And that because the next time you do
thesame experiment, picking numbers out of the bucket, the
rule that youused to re-construct the previous sequence will
be useless. If it werethat way, that random meant
unpredictability of the next digit of analready constructed
sequence, then there would be not a single randomsequence on
this planet.In exactly the same way, if there is no way of
saying what number Iıllpick out of the bucket of numbers,
then the resulting sequence ofpicked numbers is random, even
if it only consists of a single number.It getıs the lable
random out of the way it was constructed, notbecause I know
that it is 3 after having picked the number.I hope that my
random chosen vocabulary was not too random
forunderstanding.Predictabel greetings,Nick.====Hi Thomas!You
grasped the meaning right away. I keep telling about this
Ŝnedistinction of before and after the generation of the
number, butnobody seems to be listening. Random stands for
how it was made, andif we could predict what comes out,
*before* it came out, not afterit.The relationship to QM is
only of very general nature, only ananalogy, at least for our
current knowledge. With QM you can of cousemake very good
random number generators but not every random numbergenerator

happen when God divided by zero.What are the reciprocals of
transŜnite numbers, anyhow? SubŜnite numbers?HypoŜnite
numbers? Numericules? Diminutives? Speckulations? Weenies?I
agree. Furthermore, due to the quantum lumpiness of physical
reality, weshouldnıt call it a space-time continuum at all;
itıs a space-timecontiguity (we ought to call it a contiguum,
but thereıs no such word inEnglish). In a way, Pythagoras was
right; there are no irrational numbersin reality, only
integers (quanta) and their ratios. So even so-calledrandom
physical processes only have a Ŝnite number of possible
states,and hence are not truly random, but (like computer
RNGıs) can besufŜciently *chaotic* to survive the various
tests of randomness.Whatever it is, itıs all
good.-Joe-====Donıt worry; weıre listening.I agree! Numbers
contain within themselves no information regarding wherethey
came from... but it makes perfect sense to ask Is the PROCESS
thatPICKED this number a random PROCESS?Is celery a healthy
food? Most certainly not! Itıs not healthy at all:itıs DEAD!
But we *call* it healthy due to its relationship to
*our*Similarly, we call the results of random number
generators random numbersnot because the numbers themselves
are actually random (theyıre not!) butbecause of their
relationship to the randomness of the process thatgenerated
them. In other words, we think of RNGıs as
random-numbergenerators (that is, generators of random
numbers) but they are reallyrandom number-generators (that
is, random generators of numbers). I canrandomly generate a
speciŜc number, but I canıt generate a random number,unless
we agree to understand the term random number similarly to
theillogical but understood term healthy food. Donıt carry
this analogy too-Joe- -stalker-====Cantor proved for cardinal
numbers a,b that a x b = max{a,b}if at least one of them is
transŜnite. Thus, no transŜnitecardinal can have a
reciprocal. Slighly more complicatedare the arithmetical
formulas for transŜnite ordinals,but also such an ordinal has
no reciprocal.The situation changes drastically when looking
atnon-standard-analysis, a new disciplie which has to dowith
real closed extensions of the real number Ŝeld in which exist
inŜnite numbers, i.e., those greaterthat all reals. Such a
number has a positive reciprocalsmaller than all positive
reals, hence, is an inŜnitesimalin the sence of Newton,
Leibniz and Euler. With theaid of his inŜnitesimals, Euler
developed the exponentialseries for the function e^x already
on page 1 of this book!Then he takes just a little rest in
the theory to computee from e = 1 + 1/1! +1/2! + ... with a
precision of 25decimals. Eulers book shows how fast one can
attend resultsfor which at present (without inŜnitesimals) at
least 100 pages of preparation are needed :-) InŜnitesimals
were eliminated from analysis by Cauchyand Weierstra because
of lack of a logical foundation.But to the great surprise of
the classical analysis, where reintroduced in about 1960 by
Abraham Robinsonwho explored modeltheoretic methods of Alfred
Tarski.Both Alfred Tarski and Abraham Robinson emigrated
justbefore world war to from Europe to the USA. At
manyuniversities in the world, non-standard analysis
isalready taught but it will be still about a decadeto learn
on these new numbers in colleges and high-scools.-
WolfgangPS. The USA receveid so much intellectual
potentialfrom Europe before and after world-war II for
*nothing*that the should perhaps feel obliged to help the
restof the world at least in science and engineering. E====I
forgot to mention the title of Eulers bookrecommended
occasionally to my math students:L. Euler, Introductio in
Analysin inŜnitorum,Collected works, vol 8, Leipzig 1922.-
Wolfgang====Any ISBN numbers?What translations are
available?Finnish would be good, English acceptable.My
Svenska & Deutch are not good enough for math stuff.Remember,
my IQ is almost certainly below 150.====Hmm...OK. Then the
process itself must be examined thoroughly. If
afterexamination we still have no clue, then it could be that
it is arandom process, or it could be that we just canıt Ŝnd
that it is nota random process.In the case of Nick closes his
eyes and picks a celery out of Joeısbucket, I think, nobody
can Ŝnd out what makes Nick pick the one andnot the other
celery. So we call it random process. Perhaps it
isnıt,perhaps there is a fantastic equation with three
trillions parametersthat predicts that Iım going to pick the
smallest one.No please, anything else but not that! ;-)The
celery can be considered as the case of a one celeried
sequence,so it is the sequence which can be called random
sequence ofceleries. You totally confused me, Joe!
*8-SCelereatings,Nick.====Some words seem to be missing here,
like Ŝnite set of outcomes,and equally likely.But there are
two inŜnite digit sequences equal to that value,as there are
for every value expressed by only a Ŝnitenumber of digits, so
actually that kind of valuemust be twice as likely as any
other :)How do you know that numbers, as far as they might
representquantities in nature, arenıt actually all
quantized,and even all selected from a Ŝnite set in every
case?Even spatial distances might appear to be quantized,in
some theories, which if true would mean thatHilbertıs Ŝnding
more points on a line thancan be matched with the set of all
integersmight only be possible in the imagination,and not in
the physical world.Maybe itıs equal to the number of points
on a line,which you already said was more than inŜnity :)I
thought it depended only on deŜning limits of sequences.Itıs
already been pointed out that inŜnities are of various
kinds,some being greater than others, and so must there
bevarious kinds of zero. But why should engineers care?They
only know how to build Ŝnite structures,to approximate
accuracies, and leave perfection (whatever that is) to God
:)Perhaps the notion that we can conceive, in our
consciousness,of that which never exists in physical form, is
some evidence,or at least a hint, that consciousness lies
beyond the material realm.Structural and societal engineering

-[]-.====People are getting confused here, the probability of
a random numberis zero only if it is comes from an inŜnite
set. If it comes from aŜnite set it indeed has a probability
of appearing (like in the diceexample). Talking about a
sequence, it will have a non zeroprobability of appearing
only if it is a Ŝnite sequence comming froma Ŝnite set of
possible numbers (for example the sequence { 1 1 4 6 24 }
when throwing a dice.PS: Excuse me if Iım not using the exact
mathematical terms: englishis not my mother language and iım

make a few general remarks to this often discussedsubject
from the point of view of mathematic and language,with a few
remarks on the historical background.Polish notation (PN) was
not invented by Lukaciewicz alone butis a result of discussion
in and achievements of the logicalschool in Lemberg (Lw.97w in
Polish, today Lwiw in Ukrainean).At the begin of the 20th
century, that school was a centreof logical research in
Europe. PN served special tasks inaxiomatizability of
propositional logic and had been useduntil about 1950 in many
scientiŜc papers, mainly in thedomain of propositional
logic.When the basic questions of axiomatizability in logic
weresettled, also Polish logicians returned to algebraic
notationin formalized languages throughout. How to explain
this?It is a fact that our brain doesnıt like consuming
condensedinformation, like our stomac doesnıt like to consume
alcoholif not thinned below 5o%, say. In addition, our brain
doesnıtprocess information serially like a computer, but
processesit in a very complex way by making pictures on the
things.Thus, in descriptive math, no matter whether
elementary oradvanced, PN or RPN does not have the slightest
chance tobe accepted as a facon de parler. By the way,
thereıd beenonly a limited number of people like Lukaciewicz,
Tarskiand a few others who had trained their brains (like
ablind chess-player, say) to read long formulas in PN.The
situation is quite different in programming languages.Besides
in the HPs, RPN is used in several well-establishedprogramming
languages, in particular in POSTSCRIPT which isthe language
understood by all fast printers in the world.Why here RPN?
Because the translation of POSTSCRIPT intoprinting action
must be done fast and efŜciently. Thereısno time for
long-during compilation into mashine-language.The idea to use
RPN it in programming calculator was one ofthe really great
ideas of the Corvallis team. It was perhapsa kind of a game
to use it not only in programming languagesbut also in direct
manipulation of the keyboard. It was also no bad idea to
integrate both approaches in asingle operating system on the
HP49. But ACO made a basicmistake. They squeezed everything
which, by its nature, isnot algebraic, into an algebraic
pattern. The worst examplefor me is the handling of a
directory name. Why the nameis Ŝrst edited so that youıve to
press ENTER, with somemysterious NOVAL on the stack? This
sometimes artiŜcialavoiding of RPN caused that all former
HP-users refusedto use algebraic mode, not to say they hate
it :-)Also in math, from time to time the operation symbol
iswritten *after* the argument, as an exponent, for
instance.That makes operator-composition sometimes more
lucid. Stillmore so in daily life where commands are often
named andexecuted *after* the argument has been named. Thus,
itwould have been completely natural for somebody who
hasnever heard on RPN to set a directory by just pressingon
the directoryıs key.On the other hand, commands like PURGE,
ORDER, RENAMEare not RPN commands by its very nature. There
is noreason why the argument list should precede the
PURGEcommand in direct manipulation (not in programming).On
some key on my 49 there Ŝrst appears an empty inputlist named
Purge, just to be Ŝlled in to do the actualpurging. Thus, on
the level of direct action, a naturalsymbiosis of RPN and
algebra is the best approach. like computing 1+2, there is no
natural preference ofŜrst delivering the arguments, or waiting
with the +on the next argument, except for a computer itself
whoprefers to get Ŝrst the arguments for obvious reason.A
computer is always happy with condensed information.But for a
normal human being, the little pause ofwaiting for the second
argument after having gottenthe operation sign, seems to be
useful for prepartingthe brain onto the task: Aha, thereıll
come somethingIıll have to add to the already given
argument... Onthis very elementary level, it may also be
solely aquestion of habit. - Wolfgang====Which way is easiest

features all sorts of goodies for the hp49g+ that seem to

moving Ŝler over there, but thatdid not work.so iım missing

lesson since i got tired of typing in all thatpunctuation on
the hp--i can use a mac osx text editor, save in ascii,and
copy it over via the sd card. quite a few steps involved
there, butstill faster than tapping out even that short
string on the calculatoritself. and i think i discovered that
the hp is case-insensitive,converting everything to
uppercase.btw, on another topic, i noticed in typing all this

important, though. I like the feeling I get when I look at
either the 34C or 32SII or a 25C; the 48Gıs are all right,
though. I would have preferred if HP made the 49G+ look more
like a 48SX rather than the 39G/40G/49G. These latter are

assumed that with pacing only activated for SRECVthis
wouldnıt be a problem. If I was using a PIC or other
microcontroller Isuppose I could eliminate the Xon and Xoff
signals in the data by jumping overthose signals, e.g. add
00000100 to all bytes with a MSB of 1, and make asoftware
correction later. But the hardware is being built from
generic ICsand, while still feasible, adds extra complexity
and current drain. And Ididnıt know the 49g lacked pacing so
pacing will probably have to be avoidedanyway.Maybe something
like this:N Level 1, # of 255 byte blocks<< XXX Garbage
collection command 1 - 0 SWAP Sets loop size START 255 SRECV
Receives data in N 255 byte blocks DROP No error checks NEXT
CLOSEIO>> There might be a timing problem here if SRECV
automatically executes CLOSEIOand it takes longer than about
0.5millisec to execute that CLOSEIO, reenter theSTART loop,
enter the 255, and have SRECV reopen the port. If so, I can
addsome more delay time in the hardware. The real weakness is
the lack of errorchecking, and that is where the Xon/Xoff came
in. In any case Iıll certainly bedoing some PC to 48gx testing
as you suggested.Robert====>need to know can be determined by

device to the transmitting device in order to regulate the ŝow
of data coming down to it.The *transmitting* device takes no
notice of any XON/XOFF characters that happen to be in the
data stream as they are irrelevant. It only acts on XON/XOFF
characters received from the device that it is transmitting
to.-- Bruce HorrocksSurreyEngland====X> Maybe something like

You know, I get really tired ofhearing that Bush lied about
these things. Mistaken? perhaps, butlying implies a statement
of things you KNOW to be false. That has notbeen proven. It is
factually incorrect to claim Bush lied. Many inthe US, mostly
Democrats, are now making the claim that Bush lied toget us
into the war.Below are statements made by various Democrats
in the US, including AlGore, Bill Clinton and others. Were
all of these people lying as well?If not, what is the
difference between their statements and the onesBush made?
Even the UN inspectors believed Saddam had WMDs.I see no
difference at all. I think the new Iraqi Foreign Minister
hadit correct when he castigated the UN security council for
failing toact to oust Saddam after he killed hundreds of
thousands of his ownpeople, year after year. Are the Iraqi
lives that will now be savedover the next 10 years not worth
saving?Quotes (which people who say Bush lied must also call
lies):---------------------------------One way or the other,
we are determined to deny Iraq thecapacity to develop weapons
of mass destruction and the missiles todeliverthem. That is
our bottom line. - President Clinton, Feb. 4, 1998If Saddam
rejects peace and we have to use force, our purposeis clear.
We want to seriously diminish the threat posed by
Iraqısweaponsof mass destruction program. - President
Clinton, Feb. 17, 1998Iraq is a long way from [here], but
what happens there mattersa great deal here. For the risks
that the leaders of a rogue statewilluse nuclear, chemical or
biological weapons against us or our alliesis the greatest
security threat we face. - Madeline Albright, Feb 18,1998He
will use those weapons of mass destruction again, as he
hasten times since 1983. - Sandy Berger, Clinton National
SecurityAdviser,Feb, 18, 1998[We] urge you, after consulting
with Congress, and consistentwith the U.S. Constitution and
laws, to take necessary actions(including,if appropriate, air
and missile strikes on suspect Iraqi sites) torespond
effectively to the threat posed by Iraqıs refusal to end
itsweapons of mass destruction programs. - Letter to
President Clinton,signed bySens. Carl Levin, Tom Daschle,
John Kerry, and others Oct. 9, 1998Saddam Hussein has been
engaged in the development of weaponsof mass destruction
technology which is a threat to countries in theregion and he
has made a mockery of the weapons inspection process.
-Rep.Nancy Pelosi (D, CA), Dec. 16, 1998Hussein has ...
chosen to spend his money on building weaponsof mass
destruction and palaces for his cronies. - Madeline
Albright,Clinton Secretary of State, Nov. 10, 1999There is no
doubt that ... Saddam Hussein has invigorated hisweapons
programs. Reports indicate that biological, chemical
andnuclear programs continue apace and may be back to
pre-Gulf Warstatus. In addition, Saddam continues to redeŜne
delivery systems andis doubtless using the cover of a licit
missile program to developlonger-range missiles that will
threaten the United States and ourallies. - Letter to
President Bush,Signed by Sen. Bob Graham (D, FL,) and others,
December 5, 2001We begin with the common belief that Saddam
Hussein is a tyrantand a threat to the peace and stability of
the region. He has ignoredthe mandated of the United Nations
and is building weapons of massdestruction and the means of
delivering them. - Sen. Carl Levin (D,MI),Sept. 19, 2002We
know that he has stored secret supplies of biological
andchemical weapons throughout his country. - Al Gore, Sept.
23, 2002Iraqıs search for weapons of mass destruction has
provenimpossible to deter and we should assume that it will
continue for aslong asSaddam is in power. - Al Gore, Sept.
23, 2002We have known for many years that Saddam Hussein is
seeking anddeveloping weapons of mass destruction. - Sen. Ted
Kennedy (D, MA),Sept. 27, 2002The last UN weapons inspectors
left Iraq in October of 1998. We are conŜdent that Saddam
Hussein retains some stockpiles ofchemicaland biological
weapons, and that he has since embarked on a crashcourseto
build up his chemical and biological warfare
capabilities.Intelligence reports indicate that he is seeking
nuclear weapons... -Sen.Robert Byrd (D, WV), Oct. 3, 2002I
will be voting to give the President of the United States
theauthority to use force-- if necessary-- to disarm Saddam
Husseinbecause I believe that a deadly arsenal of weapons of
mas destructionin his hands is a real and grave threat to our
security. - Sen. JohnF. Kerry (D, MA),Oct. 9, 2002There is
unmistakable evidence that Saddam Hussein is
workingaggressively to develop nuclear weapons and will
likely have nuclearweapons within the next Ŝve years ... We
also should remember we havealways underestimated the
progress Saddam has made in development ofweapons of mass
destruction. - Sen. Jay Rockefeller (D, WV), Oct 10,2002He
has systematically violated, over the course of the past
11years, every signiŜcant UN resolution that has demanded
that hedisarmand destroy his chemical and biological weapons,
and any nuclearcapacity.This he has refused to do Rep. Henry
Waxman (D, CA), Oct. 10, 2002In the four years since the
inspectors left, intelligencereports show that Saddam Hussein
has worked to rebuild his chemicalandbiological weapons stock,
his missile delivery capability, and hisnuclear program.He has
also given aid, comfort, and sanctuary to terrorists,
includingalQaeda members .. It is clear, however, that if
left unchecked, SaddamHusseinwill continue to increase his
capacity to wage biological andchemical warfare,Clinton(D,
NY), Oct 10, 2002We are in possession of what I think to be
compelling evidencethat Saddam Hussein has, and has had for a
number of years, adeveloping capacity for the production and
storage of weapons of massdestruction.- Sen. Bob Graham (D,
FL), Dec. 8, 2002Without question, we need to disarm Saddam
Hussein. He is abrutal, murderous dictator, leading an
oppressive regime ... Hepresents aparticularly grievous
threat because he is so consistently proneto miscalculation
... And now he is miscalculating Americaısresponse to his
continued deceit and his consistent grasp for weaponsof
massdestruction ... So the threat of Saddam Hussein with

was clear enough, eventhough Saddam did his best to hide it.
It is not a lie that theactual weapons havenıt been found

Samuel!There should be no objection from HP to release a ROM
for the old 49GThe new model is so much faster nad better in
many ways that this would notharm in any way the sales of the
new fast machineand would keep the old customers happyMaybe
they could release a beta 1.23 or 1.25? (for both

programs are not signed by TI, only FLASH applications.
FLASHapplications can be made so that they require a key to
install, whichstops people from pirating them. It seems that
TI believed that allthe FLASH apps they sold would be over
24k. With the limit in place,it would not be possible to
pirate a FLASH app by somehow convertingit to an asm program
which requires no signing.====> reasons I donıt even pretend
