The Set Automatic Unshelving service controls whether a process
    automatically unshelves files.

    The pidadr and prcnam default to the current process. If the
    longword at address pidadr is 0, the PID of the target process is
    returned.

    The setting for automatic unshelving is inherited by
    subprocesses.

    The DCL command SET PROCESS/[NO]AUTOUNSHELVE also controls
    automatic unshelving for a process; for details, see the VSI
    OpenVMS DCL Dictionary.
