VMS Help V73 Features, Programming Features, Multiprocess Debugging (Alpha)  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    For Version 7.3, debugger support for multiprocess programs has
    been extensively overhauled. Problems have been corrected and the
    user interface has been improved.

    The multiprocess debugging enhancements include the following
    features:

    o  Greater control over individual process and groups of
       processes, including:

          Execution of processes (or groups of processes)
          Suspension of processes (or groups of processes)
          Exiting processes (or groups of processes), with or without
          exit handler execution

    o  Ability to create user-defined groups of processes

    o  Easier to start a multiprocess debugging session; the default
       configuration of the kept debugger is for a multiprocess
       session

    o  Applications that use $HIBER WAIT (LIB$WAIT, $SCHDWK, and so
       on) can now be debugged in a multiprocess debugging session

    These enhancements make it much easier to debug multiprocess
    programs.
