42S statistics registers

Flags 61, 62 and 63 will however only be set the first time you use Σ+.
So I shamelessly (but gratefully) copied your program, but I use

Code:

 FS? 60
 FS? 61 (62,63 as appropriate)
 GTO 99

to test for Invalid recall requests.

BTW where did you find this info on flags 61-63?

Cheers, Werner

That's a good point. Note that you'll need to change the flag tests like this if you want an "or" condition that goes to 99 if either flag is set:

Code:

FC? 60
FS? 61
GTO 99

I believe I got the flag info from the 42S manual, bottom of page 279, as well as by experimenting to see exactly how those flags behaved.
