Class
Keyboard Events
Purpose
Determine what happens when the interrupt key is pressed
Syntax
SET DOESCAPE ON | OFF | (<expL>)
See Also
INKEY(), ON ESCAPE, ON KEY, SET ESCAPE
Description
If SET DOESCAPE is ON, and ESCAPE is ON, and a command is executing in a program file, when the interrupt key is pressed, the command is canceled and execution of the program continues with the next command. The DOESCAPE command differs from the ESCAPE command in that interruption of a program only cancels the current command being executed. If ESCAPE is OFF, SET DOESCAPE has no effect. By default, DOESCAPE is OFF.
Example
//program longsort set doescape on set escape on sort on name /a, event /d, date /a return use patrons do longsort
