HP-42 Program Critique - Kinematic Equations (first program)

[DM48]

I've been writing small programs trying to get a feel for different areas of Free42/DM42.

Here is my version for the Kinematic equations (three instances). On the menu, the first variable listed is the data you have -> the data you want. Time -> Distance for example.

Don't hold back and let me have it. I welcome any and all suggestions and corrections. My biggest obstacle at the moment is understanding when to use GTO vs XEQ. The difference is GTO goes and stops unless you point it somewhere else to go and XEQ executes and comes back and continues on.

In the early days experimenting with the Menu layout and just have a 1 + option XEQ seemed to fail after four pushes of the soft key. This is why I used GTO here.

Many thanks in advance!
