VMS Help SHOW, PROCESS, Qualifiers, /IDENTIFICATION  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /IDENTIFICATION=pid

    Requires GROUP or WORLD privilege to access processes other than
    your own.

    Displays information about the process with the specified process
    identification (PID). The PID is assigned by the system when
    the process is created. When you specify a PID, you can omit the
    leading zeros.

    If you specify the /IDENTIFICATION qualifier, it overrides the
    process-name parameter. If, in addition, you specify the /MEMORY
    qualifier, the PID value must be that of the current process.
