occasional checking process is alive

        Please excuse this newbie question:

        Preamble:
        I have a simple-minded STk GUI which creates input for a
      process. When the data are in an appropriate form, the STk
      program writes it to a file and starts a subprocess (which may
      or may not fail horribly).

        What I would like to do is every-so-often check to see if the
      process is still alive (pressumbably using (process-alive?
      *process-num*)). If it is not then do some action (such as
      (my-popup "Job terminated")). It would be good if I could check
      the exit status of the program and I could change the popup
      message appropriately. I'm guessing I need some sort of (after
      ..) or (tkwait ..) thing - but I don't see how to do it...

        Can you help?

        Thanks,

        Paul
