SET ESCAPE
 Toggle Esc as a READ exit key
------------------------------------------------------------------------------
 Syntax

     SET ESCAPE ON | off | <xlToggle>

 Arguments

     ON enables Esc as a READ exit key.

     OFF disables Esc as a READ exit key.

     <xlToggle> is a logical expression that must be enclosed in
     parentheses.  A value of true (.T.) is the same as ON, and a value of
     false (.F.) is the same as OFF.

 Description

     If SET ESCAPE is ON, Esc terminates the current READ.  Any changes made
     to the current Get object are lost, and validation with RANGE or VALID
     is bypassed.  When SET ESCAPE is OFF and the user presses Esc, the key
     press is ignored.  With SET KEY, however, you can reassign Esc for
     special handling, regardless of the status of SET ESCAPE.
