HP50G Programming - display list/matrix and show program

[dizzy]

Hi all,

I'm new here and new to the world of HP calculators and I've spent the last few days lusting after various calculators from HP. I'm trying to get a handle on what's possible with the Prime and hp50g before making the difficult decision on which to buy.

Anyway, on to my questions. Hopefully this is a suitable place to ask.

Q1: Is there a way to invoke the matrix editor (MTRW) programmatically on a given list/matrix? I want to show the user a (potentially) long and expanding list at a few points in my program.

Q2: I'd also like a nice way to display the "source" of a program programatically. By this I mean the little listing enclosed in chevrons which resides on the stack immediately after entering a program. I have a program stored in a variable (which can be evaluated, etc.) which I want to display (potentially the user will edit it) and certainly don't want to have to go fishing through the files listing.

Thanks in advance!

I got there in the end. Problem solved.

We'd be interested in how you got there. Can you post some code here, please?

Sorry, I didn't see your reply until now.

The matrix editor can be opened with EDITB (if a Matrix is on the stack).

Showing a program is easy too: Just STO it into a variable and then RCL it.

Hi all,
if you are still interested, these instructions are used for call the matrix writer inside a program:

#A2012h LIBEVAL A STO @ create a matrix and store it in a variable (A)

A @ view A

If you want edit the matrix, alwais inside a program, use these instructions with a soft menu for example:

A
35.1 KEYEVAL
'A' STO

Best regards
