How do I get the my current APPX Process ID

======================================================================
SUBROUTINE  Process Name:     GET PROCESS ID

      GOSUB    --- GET CONFIGURATION INFO
      SET      --- CONFIG TYPE                =      PID
      READ     --- CONFIG                 HOLD 0      BY CONFIG TYPE
F     CANCEL    unexpected error trying to READ "--- CONFIG"
      SET      --- TEMP 32                    =  --- CONFIG DATA
      *        --- TEMP 32 contains the unique Process ID
