HP48G soft menu toggle: How?

[DM48]

John, thank you for the response and I am glad to hear you are progressing with your recent surgery. Most of my neighbors have had a hip replacement of some kind and it has been amazing to watch the recovery progress improve drastically over the years.

The program I am creating at the moment is very simple. It is to teach me what I need to do. I also understand the use of "helper" programs you suggested while in this learning phase. This makes good sense.

When my program starts up, it checks to see if the FLAG has been set or not. It then gives the soft menu item the correct flag status on item. I am not understanding how to refresh the menu without writing another sub-routine to do exactly that and no more. Is this correct?

Program Starts
Menu created
Key pressed that changes the flag
Program calls upon sub-routine to create the menu

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.
