The following table describes possible values of STARTUP_P1
    through _P8:

    STARTUP
    Value          Description

    STARTUP_P1     Specifies the type of system boot the system-
                   independent startup procedure is to perform when
                   STARTUP_P1 has one of the following values:

                   o  " "- A full boot is performed.

                   o  "MIN"- A minimum boot that starts only what is
                      absolutely necessary for the operating system
                      to run.

    STARTUP_P2     Controls the setting of verification during the
                   execution of the system-independent startup
                   procedure, STARTUP.COM, when STARTUP_P2 has one
                   of the values described in the lists below.

                   STARTUP_P2 can be one of the values shown in the
                   following list:

                   o  F[ALSE], N[O], 0, " "-Verification is not
                      enabled; in other words, NOVERIFY is performed.

                   o  T[RUE], Y[ES], 1-Verification is enabled; in
                      other words, a SET VERIFY is performed.

                   Alternatively, STARTUP_P2 can be a string
                   containing one or more of the letters shown in
                   the following list:

                   o  C-Display various checkpointing messages during
                      startup.

                   o  D-Log (or Dump) the output from the startup to
                      a file called SYS$SPECIFIC:[SYSEXE]STARTUP.LOG.

                   o  P-DCL verification is enabled for each
                      component file, but not for the startup driver.
                      If both P and V are used, P is ignored.

                   o  V-Full DCL verification is enabled; same as
                      TRUE.

    STARTUP_P3     Beginning in OpenVMS Version 7.2, if STARTUP_P3
