HP48G soft menu toggle: How?

I am not understanding how to refresh the menu without writing another sub-routine to do exactly that and no more. Is this correct?

1. Program Starts
2. Menu created [ed. by a single subroutine]
3. Key pressed that changes the flag
4. Program calls upon sub-routine [ed. from step 2] to create the menu

With my editorials above, that's pretty much how I'd do it.

Quote:It seems from the above I have to code this up twice. Is this about the go of it? I was hoping I was not looking at this correctly.

No, no need to code anything twice. I'm a software engineer and my dictum is "coding anything twice is bad." Any given functionality should have its home in only one place: then if you change it later, it changes everywhere. Strive to make each separate routine or function general purpose -- this helps. The "code only once" precept is also good for figuring out what code should be split out into a subroutine.

Does that make sense?
