PREEXIT functionality?

[Ken Langendock]

The only way I can think of being sure of what you want is to introduce an
"invisible" screen that calls this screen you want to test. You would pass a
flag to the called screen that could be tested in the calling screen. That
would push them back into the screen again for a reminder.

I.e.

Screen hidden

Procedure internal call-screen
Begin
  run screen LaunchScreen &
      passing stuff, &
              t-jobrun
End

Procedure initialize
Begin
  let t-jobrun = " "
  do internal call-screen
  if t-jobrun ne "Y"
     begin
     let t-jobrun = "N"
     do internal call-screen
     end
End
 


Screen LaunchScreen
Blah blah blah

Procedure initialize
Begin
  if "N" eq t-jobrun
     then warn "You dummy, you didn't run the job"
End

Procedure designer job
Begin
  let t-jobrun = "Y"
  ...
end


I used this approach when I had a screen that MUST tally up to 100%, even if
it crossed multiple screens. This allowed me to keep the user in the screen
until they satisfied my edit (the difference is the screen call was in a
loop).

It would be nice if there was a PREEXIT procedure available in QUICK. At
times, you want to do a final check of things before the user exits so you
can slap him upside the head if he forgot something. Unfortunately, the EXIT
procedure is not a good place to do much because Powerhoose has shut down a
lot of stuff in preparation for leaving the screen. A lot of things won't
work or won't work consistently.

Is there a workaround to replicate the functionality of a PREEXIT procedure?
