SSETBREAK()
 Sets and checks the DOS BREAK switch
------------------------------------------------------------------------------
 Syntax

     SSETBREAK([<lNewSwitch>]) --> lOldSwitch

 Argument

     <lNewSwitch>  Designates the new setting for the DOS BREAK switch.

 Returns

     SSETBREAK() returns the current BREAK setting when no parameter is
     specified; otherwise, it returns the previous setting.

 Description

     Normally, DOS only checks screen and keyboard functions for the
     Ctrl-Break key combination.  If you want to check more frequently
     (i.e., during disk operations), use SSETBREAK() to turn on the BREAK
     switch.

 Note

     .  You can also use BREAK= <ON|OFF> to set BREAK in DOS

 Example

     Activate BREAK and save the old status:

     lOld_Break  :=  SSETBREAK(.T.)
