VMS Help V73 Features, Programming Features, New Process Dump Tools (Alpha), Security and Diskquotas  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    A process dump is either complete or partial. A complete process
    dump contains all of process space and all process-pertinent data
    from system space. A partial process dump contains only user-
    readable data from process space and only those data structures
    from system space that are not deemed sensitive. Privileged
    or protected data, such as an encryption key in third-party
    software, might be considered sensitive.

    In general, nonprivileged users should not be able to read
    complete process dumps, and by default they cannot do so.
    However, certain situations require nonprivileged users to be
    able to read complete process dumps. Other situations require
    enabling a user to create a complete process dump while at
    the same time preventing that user from being able to read the
    complete process dump.

    By default, process dumps are written to the current default
    directory of the user. The user can override this by defining
    the logical name SYS$PROCDMP to identify an alternate directory
    path. Note that the name of the process dump file is always the
    same as the name of the main image at the time the process dump
    is written, with the file extension .DMP.
