ID: Q92963

The information in this article applies to:

Microsoft FoxPro for MS-DOS, versions 2.0, 2.5, and 2.5a
Microsoft FoxPro for Windows, versions 2.5 and 2.5a

An ON ESCAPE routine is called when the user attempts to interrupt program execution. An application can disable the ON ESCAPE routine with the SET ESCAPE OFF command.

An ON KEY LABEL ESCAPE routine is called when program execution has stopped and the application is waiting for user input. This routine is called regardless of the SET ESCAPE setting.

The following sample application demonstrates the differences between the ON KEY LABEL ESCAPE and ON ESCAPE commands:

   ON ESCAPE WAIT WINDOW 'On Escape'
   ON KEY LABEL ESCAPE WAIT WINDOW 'On Key Label Escape'

   WAIT WINDOW 'Press Escape While The Counter is Incrementing' NOWAIT

   FOR x = 1 to 500
      ?x
   ENDFOR

   USE customer
   WAIT WINDOW 'Press Escape after BROWSE window is showing' NOWAIT
   BROWSE

   ON KEY
   ON ESCAPE
