HP48G soft menu toggle: How?

[DM48]

Joe, thank you kind sir. I just ran some tests on my 48G and it’s perfect. I’ve not really used GROBs in a program before so now I have to figure out how I want to handle this tiny program I have written for me and my son.

I have four soft menu keys for the kinematic equations.

t->d
d->t
t->Vf
Vf->t


I want to have a SI and ENGL option for units. Do most people toggle the soft menu and just change a state of a flag (20 for example)? And use CASE statements from there? Just high level thinking here.
