New 50g, ? Entry Table?

New 50g, ? Entry Table?

2006-12-13 by artkennedy13

Just got it. I'm liking it.

Here's a puzzle. The 48g series had an EDIT key that allowed you to put
an object name in LEVEL1 and then edit it. With the 50g there is no
such? I know . . . just use the file manager - but I want to do it the
OLD WAY. Remember the VISIT key on the 48S series?

Is there a list of ROM Entries for SYSEVALs out there somewhere? Do
most of the 49g calls work?

Is there a way to switch key functions. i.e., I would like to have the
CUSTOM key be like the old CST - one stroke instead of two.

Awwww . . . now I'm finding myself hitting [ + ] instead of [ ENTER ]
when I'm using a 48. Damn!

The EDIT function is assigned to down-arrow, and edits the contents of
whatever is on top of the stack. After trying a 48G in emulation,
that's the same behavior as the EDIT key (which was assigned to
left-shifted change-sign). EDIT and VISIT are also in the CATalog, and
naturally can be assigned to any keystroke.

If you want to edit what's STORED in a object whose NAME (within single
quotes) is on the stack, you could write a tiny program: << DUP RCL EDIT
STO >> and assign THAT to a key...

Of course there's such a list. Try http://www.hpcalc.org (it's in the
Emacs package among other places) Lots of tutorials there, too.

I have to agree -- I use CST much more often than MODE, although I can
see HP's reasoning; MODE is more necessary when learning what the
calculator can do after first opening the box... I suggest reading the
manual to see how ASSIGN works, which will allow you to swap the
functions around however you like. (By "the manual" I mean the HP-50G
User's Guide, found on HP's web site and hpcalc.org, not the little
manual that came with the calc.) Please also note that your can create
a program to put in a object called STARTUP in your home directory that
always runs on after resets, and that program can turn your USER
keyboard on so you don't have to remember to do that after reseting.
USER keys on is flag -62, so your STARTUP program could be: << -62 SF >>

Also you may want to look at a package called KeyMan. By adding "long
presses" to the keystrokes, you could assign even more options to a
given key. I have trouble remembering a dozen different things that one
key can do, so I don't use it, but you might like it. As it is, I have
several keys overloaded with shift-hold combos. For instance, UnitMan's
menu is on right-shift-hold 6, and UTool is on left-shift-hold 6.
UnitMan and UTool are both on hpcalc.org.

Sorry, can't help you there! ;)

Hello.

In RPN mode, quote the variable that you want to edit with a tick
('), like 'Y' and press enter. To edit the contents of the variable,
just press left-shift (LS) down arrow. This will edit the variable,
replacing what's there.

Regarding the system entries, there are a few resources available.
All are available from www.hpcalc.org. I use emacs 2.11a, which is
an editor that includes extable2.lib, an extended sysrpl table. Also
install Nosy 4.1 and SDiag (on an SD card) and you'll be in top form.

SDiag includes a ton of text information about the calculator's entry
points, stack diagrams, etc. It can then be decompiled using Nosy
and one can see how the routines are written. Also in SDiag is an
entries browser, which not only lists about every SysRPL entry, but
includes most (if not all) of the UserRPL entries, with cross-
references and links when appropriate to the CAS help facility.

Have fun,
Scott

Regarding CUSTOM: You can always use USR entry mode on the keyboard
and assign the CUSTOM menu to the unshifted MODE key.

Yes, I had the same issue regarding the [+] key and [ENTER] keys; plus,
the alpha and Greek layouts are different.

Cheers,
Scott
