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

    The /PROCESS qualifier uses the value of the process type field
    to select records for processing. This field is present only
    in records of type IMAGE and type PROCESS. For records of type
    IMAGE, this field contains the type of the process in which the
    image was executed.

    The /PROCESS qualifier selects only records that match the
    specified types of process. If you precede the list with a minus
    sign, it selects all records except those for the specified types
    of process.

    See also the /TYPE qualifier, which selects or rejects specified
    types of record.
