Perhaps you can you use the built-in SI / ENGL toggler for this: Press right-shift 3 and see them on the F1 and F2 keys. They control flag 60 (clear = SI, set = ENGL), so your programs can test flag 60 (that's positive 60, a "user flag") to see which mode is set. This would obviate the need to program your own mode-switching softkey.

EDIT -- Oops, I just noticed that you mentioned this in your original post. Sorry if I'm misunderstanding your programming goal.

Joe, you filled in a big gap for me with the Flag 60 information. I didn't realize the SI and ENGL were calculator wide. For some reason, I just assumed it was contained to the EQ LIB. Thank you sir.

I am making our own little Kinematic program to teach my son (young) how to write programs. We are progressing to the point of using units and we thought it would be nice to have the SI and ENGL toggle on the soft menu.
