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
