Program menu; key press remembered?

[jthole]

When I define menu keys in a program with KEYX or KEYG, are the key presses stored in a register?

That means I could do something like this:

"CHOICE 1"
KEY 1 XEQ 01
"CHOICE 2"
KEY 2 XEQ 01
...
LBL 01
<retrieve key number pressed>
<do something with the key number>
RTN

instead of having each key press jumping to its own label.
(Yes, I used the search, and read the manual, but couldn't find it.)

Thanks!

How about using a flag to differentiate between two alternatives?

No. You can check whether or not Shift was pressed by testing flag 64, but for which key was pressed, the only information you have is which LBL was called.

(The flag 64 thing is a DM42/Free42 feature. It does not work on a real HP-42S or in Emu42.)

In my case, I have five alternatives. I am going to use five different labels, and calling a common subroutine from there (with different values, of course).

Thanks @Walter and @Thomas Okken!

Could each key store a different address in a register rather than XEQ and then do an indirect jump to that address?

Maybe a possibility, but I am not sure that improves my current code. I think I am not going to spend more time on it now
