50g

I have been tying to understand how to use Debug4X but I am having
trouble with my mind grasping all that is going on there.

I remember some debugging tools built into one of the old HP
calculators that allowed you to step thru a program and see what
happens to the stack as you step through it word by word. is something
like that available on the 50G?

any help apreciated.

Best regards
