Activating Lockup now



In OS/2 WARP 4 you can use the new setup string MENUITEMSELECTED to force 
a lockup of the desktop: 

 
/* ------------------------------------------------------------------ */
/* LOCKUP.CMD - force a desktop lockup now                            */
/*                                                                    */
/* (only possible in WARP 4!!!                                        */
/*                                                                    */

  call rxFuncAdd 'SysSetObjectData', 'REXXUTIL', 'SysSetObjectData'
  call rxFuncAdd 'SysOS2Ver', 'REXXUTIL', 'SysOS2Ver'

  if SysOS2Ver() < 2.40 then
  do
    say 'Sorry, this program needs WARP 4 or above!'
    exit 255
  end /* if SysOS2Ver() < 2.40 then */

  call SysSetObjectData '<WP_DESKTOP>', 'MENUITEMSELECTED=705;'
exit 0
