1  USE
   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.

   The parameter specifies the source for both the parameter
   values and the startup command 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
 

2  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 x86 systems, the system parameter file is
   SYS$SYSTEM:X86_64VMSSYS.PAR.

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

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

2  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 the ASCII string "MIN".
