Re: Catching F3/F12...

Brad,

It's probably handled the same way that we do it:

Program A displays the list panel where you type the choices.

As the program does the READC through the subfile, for each option
taken, program B is called to perform that function.

Program B also returns a value to indicate (no pun intended) if the user
pressed Enter/F3/F12 or whatever.

In your example, the member display is done -between- doing each READC.

Our standard code looks something like this:


  Columns . . . :    1  71           Browse
WYATTERP32/QPGMSRC
  SEU==>
GLNOWRKX
  FMT *  ..... *. 1 ...+... 2 ...+... 3 ...+... 4 ...+... 5 ...+... 6
