I would like to run subroutine if user presses escape key to exit window. How do I determine and trap a key pressed ?

Any suggestions would be appreciated.

Thanks

Dave

If this is a collector window just use the Save Code Command. Select an unused column number and set it to "1". Then examine that column number in @PSEUDO in the calling program.

Using column number 9:

C @RECORD=1"

is in Collector Save Code Command.

FWIW, determining whether a user pressed escape in a window can be complicated, for example by whether they clicked the exit button with a mouse. Checks with Esc.To.Exit() won't always catch this.

A good alternative for collectors is to have a SAVE process set a flag (most conveniently in a window register) which can then be checked by the POST APPLICATION process. If the flag isn't set, then the user didn't save, and so they must have "pressed Escape".
