your monitor code will not run in the following situations:
  - you call a COBOL program and it uses STOP RUN to exit.
  - the called procedure sends an *ESCAPE message back to the caller
of your procedure
  - the job is ended

you want your exception handling code to handle all exceptions.  try
finally does that. monitor end-mon does not.  ( actually I am not sure
if try finally does handle all exit situations.  I just know that
monitor ... end-mon does not. )
