Initializes the SYSGEN work area with system parameter values
    and the name of the site-independent startup command procedure,
    overwriting existing values. The initial values of the SYSGEN
    work area when the utility is invoked are the active values.

    Specify the source for both the parameter values and the
    procedure name. They can be retrieved from a parameter file,
    the current system parameter file on disk, the active system in
    memory, or the default list.

    Format

      USE  file-spec

1  –  Parameters

 file-spec

    The file specification of a system parameter file from which
    data is to be retrieved. You can use the SYSGEN command WRITE to
    create the parameter file. The default file type is .PAR.

    In place of a file specification, you can specify one of the
    following keywords:

 CURRENT

    Specifies that source information is to be retrieved from the
    current system parameter file on disk.

    On Alpha systems, the system parameter file is
    SYS$SYSTEM:ALPHAVMSSYS.PAR.

    On Integrity servers, the system parameter file is
    SYS$SYSTEM:IA64VMSSYS.PAR.

 ACTIVE

    Specifies that source information is to be retrieved from the
    active system in memory.

 DEFAULT

    Specifies that source information is to be retrieved from the
    default list. The USE DEFAULT command initializes the SYSGEN
    work area with parameter values that are built into SYSGEN;
    these values allow the operating system to boot on any standard
    configuration.

    To avoid starting all layered products on a system that is not
    tuned for them, possibly causing the system to hang, set the
    STARTUP_P1 system parameter as follows:

    SYSGEN> SET STARTUP_P1 "MIN"

2  –  Qualifiers

    None.

3  –  Examples

    1.SYSGEN> USE SYS$SYSTEM:SPECIAL

      This command uses the existing parameter file
      SYS$SYSTEM:SPECIAL.PAR.

    2.SYSGEN> USE DEFAULT

      SYSGEN> SET STARTUP_P1 "MIN"

      The first command initializes the SYSGEN work area with default
      parameter values. The second command sets the STARTUP_P1 system
      parameter to "minimum."
