This may be the problem. I don't own a 48, but I think it doesn't have
hardware flow control on IR either (the 49 doesn't have it on wire,
that's for sure). Try XON/XOFF (software).

There are a couple of commands which will display text, one
of which is not in the
manual (a late entry).
1.  DISP n;text
This displays the text on line n (of 7) on the screen.  It
is quick and easy but
very annoying because it wipes the entire line before
writing the text.  This means
that you can't use it to (for example) label a graph as it
destroys the image you're
writing on.  You also can't write part of a line and then
come back later and add to
it.
2. MSGBOX
This pops up a message box containing the text.  It is quick
and easy but the font
is not adjustable.  eg  MSGBOXPress ENTER to finish:
3. Store the image as a GROB and edit.  (NOT recommended)
This method is VERY slow and clumsy. If you're working on
the 38G or want your
program to be portable to a 38G you have to use it as the
next command (DISPXY) is
not available on the 38G. Basically you capture the image to
a GROB (graphics object
G0..G9), convert your text to another GROB, superimpose the
two and then redisplay
the new image.
Eg.
  REPLACE Page;(Xmin,Ymax);G1:
Suppose M=2 and C=3.  This program will capture the PLOT
screen last displayed,
create a GROB G1 containing the equation Y=2X+3 and
superimpose it onto the plot
image then redisplay on the screen. Note the QUOTE( ) around
Y and X so that the
symbols are used instead of the values.
4. DISPXY
This was a command that JYA added to the calculator too late
to go into the manual
although it does appear in the CMDS menu.  It was something
that I'd been pleading
with him to add all along and I think he either took mercy
or more likely did it to
get me to finally shut up :-). This command is really great
as it allows you to
write text directly onto an (x,y) coordinate on the screen
(coords determined by
current plot settings of active aplet) using a couple of
different fonts. It is VERY
easy to use and makes the aplets/programs run much faster
too.
Here's the same code as the previous example, done using
DISPXY.
  DISPXY Xmin;Ymax;1;y=Mx+C:
You can find more information on DISPXY on my FAQ page at
http://members.iinet.net.au/~ccroft .  See question #64.

This is interesting. It appears you may have stumbled upon a real
rarity : a bug in the 48-R  . The problem stems from the fact that
xPi is not a number. Rather, it is a small secondary that determines
( based on the system flags 2 and 3 ) whether it should push the real
number %PI to the stack or the symbolic SYMBOL xPi ;. This causes no
problems when you hit the keys for Pi because in that case the
secondary is evaluated. But when you enter Pi into a list at the
command prompt it is not evaluated so that when x* encounters xPi in
the list it errors out because a secondary is not a valid argument
type.
  
neat how you can put either of these into an equation with EQW,
in function notation =)  I'll have to try, a little later, to
is.
One thing I'd like to do though, is be able to put in the
function (f+g), as in the subject where 'x' is given to it.
This is a notation my calculus teacher used recently; it's
equivalent to 'f(x)+g(x)', and I imagine that more interesting
operations than addition can happen when you build a function
in that manner.  EQW doesn't seem to accept it though.  Is there
a simple way to put (f+x)(x) into EQW, in a manner that would
evaluate correctly?  I'm thinking of having an algebraic-object-
modifying function 'Q' that would translate (f+g)*(x) to
'f(x) + g(x)', but I'd like to know if there was another way.

I know that, but thats not the point. Shouldn't the BASIS command 
depend
on flag -98, so that if you express your vectors vertically, then you
should get r vectors with n elements, and if you like the vectors
horizontally, you get r vectors with m elements. 
 
A steep easier/simpler would be: a*(5*b^9*c^13)^(1/5)
 
Or run the little ASMs from Keyman:
There you have the choice to assign LSH SPC r~¡ ?

which means:

left-shift-hold long-pressed-space toggles between rectangular and

I assume it toggles a flag, so, it could work different when you
are in grad mode or you are working with spherical coordinates,

I have two 115k byte objects one is is port 0, the other is in the
Home directory.
I have 550k bytes free in Port 2.  When I try to save the object that
is in the Home directory into port 2, I get an out of memory message.
I know that the calculator may try to use port 0 temporarily when Port
2 is almost full, but in this case there is plenty of space.
Can someone explain what is going on.
 
I'm having this kind of problems. Normally they are because even if I 
get
400KB free in port 2 there is no 128KB flash bank free for store a new 
large
object. The flash is divided in banks of 128KB and you can't store an 
object
bigger than that but as well the objects are stored there in an way 
that
makes posible to have all of the banks used with a small object reducin 
the
possibilities of storing big objects.
For that we need a defrag tool. Currently I do it manually: moving 

objects
between the three ports until I got what I want, not always I'm lucky.
Other possibility is that the calc is trying to make a copy of the 
object
before stoing it in port2, like there is no sufficent memory for doing 
so...
Could you try to directly backup the HOME to port 2 or your HOME is 
bigger
than 128KB? I you can. then you will got the object you want in port2, 
but
inside a directory of all home. But then in that situation you can 
clear
your home, recall the object from the backup in port2 and store it in 
port2
on it own. Then restore the home from the backup and delete the backup.
 
The flash memory is divided in one port of 64kb and 8 ports of 128Kb. 
What may happening is that the 550Kb free that you have in port 2
don't have a contiguous 115Kb in one port or if there is a possibility
to free this space,
he calc can't complete the procedure because it has ~26 Kb of free
memory.
Try to free the Home memory or the P0 memory moving some objects to
Port 1
and try again the operation.
 
 
This is interesting, but why do you purge 'NED'?

Of course it needs to be changed. A CAS must be able to respond well
to inappropriate input. It should hopefully give an error message to
indicate what is wrong (e.g. Recursion limit exceeded), but no
matter what you give it (non-rectangular array or exact input or
whatever), it should not crash.

solver libraries, such as eql49, eqslv. I would say they are pretty
good. But none of them could call up the HP built-in equation solver
directly. For example, when you press the soft key SLV while using
eql49, the equation will be stored in variable EQ, then you need to
mannually start the builtin equation solver to solve the equation. I
thought, based on the document provided by the author, that the
equation solver screen should pop up when I press SLV. Any comments
would be appreciated. Does anyone know or have an equation library
with which you can add your own equation categories and equations, and

(snip)
Algebraic isn't a dead-end mode, at least not for many people who
use it on TI calcs, and I've heard that people use it on the 49G,
so apparently it has some purpose.  I've only very briefly used
algebraic mode on the 49G -- I find it horribly annoying, as I'm
used to being able to enter data, modify data, fetch data, do
various manipulations on data, and maybe eventually send data to
a specific function.  Having to do this all in one step, or using
the ANS command, would drive me mad.  This is habit, surely, but
I and others are very sincere about it.  There's been much
discussion on the points between algebraic and RPN, and you can
read some of it by searching at

I, like wolfgang ;), have used this method too (FEM48 library).
Personally I have compressed a lot of the libs (mainly Structural
Engineering libs written by myself) on my HP48GX (with 2 RAM cards). In
fact, I have written a library (BZLIB) that automates the task!
(note that this does not check the speed relevancy of the subroutine 
that
will be compressed)
It compresses every subroutine (not xNAME's !! because of argument 
checking)
if this yields a size decrease and adds the UBZ decompresser to the 
library.
This way the lib is self-sufficient.

Alpha RightShift 6.  Lots of things seem less convenient on the 49G.
James
Position of the right-shift angle symbol on the
49 is hardly an example of lesser convenience.
Those who were used to the 48 keyboard must just
accept that symbol location on the 49 is different
from that on the 48 :-) 
Questions like where is this or that symbol are
superflue because the character browser on right
shift CAT gives complete information. For SysRPL
programmers the HP49 symbol location may be even
more convenient; they quite often need the symbols
unavoidable anyway because the arrow keys do not
carry symbols anymore, a considerable advantage.
There may be more serious reasons for complaining on
the 49 keyboard layout but this subject was discussed
in the past years in great detail already :-)

Dont't open your 49. That is extremely risky.
First of all, if you guess there is a mechanical
defect, press with you thumb fairly strong on 
the black part beneath the screen (where you see
the HP 49G imprint). That's the region where the
keys are connected to the chip. If this doen't
help, with high probality you got a software
black-out. That may perhaps be caused by ice-cube.
Just purge all suspected libraries from your ports.
If this does not help, upgrade your baby to the
newest ROM: 19-6. If you did it already, do it
again because some over-complex tools may even
spoil some ROM banks! (Play TETRI instead of
ice-cube. That will by sure not spoil anything
in your RAM or ROM :-)
If you have trouble with your keys to press
ENTER, + and ON simultaneously, use a paperclip
to get the No System menu.

Opening it is pretty easy -- after removing the batteries you'll see 6 
heads
of plastic rivets (aka heat stakes) in the bottom of the battery 
compartment.
Use a 4mm drill operated by hand and drill the heads off, <1.5mm deep.
Carefully start to pull apart the case near the battery compartment, track 

the
batteries + contact -- it may be neccessary to slightly bent in 
towards 
the -
contact to unlink it from a small plastic hook that is part of the case. 

Apply
some force w/ a fingernail in the groove between the case halfs near the 

DEL
key-row, left and right, to unlink the hooks. Work towards the LCD w/ 
the
fingernail along the lower edge (towards the bottom) of the big groove 
(where
the cover slides in) to unlink two smaller hooks on each side. Carefully 

lift the
bottom further unless the two big hooks around the serial connector 
release
the bottom. To get rid of the acid, I'd suggest to _carefully_ rinse the 

thing w/
a few liter of destilled water (try not to get the LCD region wet) and let 

it dry
out for at least a day, then reassemble and test the unit.

You will find a lot of information concernig the programming of the HP49G 

on
www.hpcalc.org. .UserRPL (RPL : Reverse Polish Lisp) is the 
easiest and

therefore
learned first, before touching anything else. There is a great tutorial 
for
beginner written bei Eduardo M. Kalinowski available on hpcalc.org. So 
I
recommend you learn UserRPL first and then come back and ask for more.

  SubRPtr makes a list of all the Rompointers (from the same lib)
  that are used by a command.

  because XLIB 1000 2 is used by Test
  When SubRPtr is done on TestTwo it returns
  {Test XLIB 1000 2 XLIB 1000 3} because XLIB 1000 3 is used by
