The command for the SYSGEN utility is SYSGEN. SYSGEN has four positional parameters: 

   SYSGEN    [  basegroup]
             [ ,newgroup ]
             [ ,inputfile   ]
             [ ,outputfile  ]
The basegroup parameter specifies the group in the SYS account that contains the configuration data file set to be used or changed. The default base group is the group used to boot the system (usually CONFIG). The default base group is the group specified in the initial system load (ISL) START command line. (For information on specifying configuration groups during START, refer to Chapter 3 System Startup Functions)

If you attempt to specify a nonexistent group using the BASEGROUP command, SYSGEN issues the following message: 

   **error** group groupname does not exist
The newgroup parameter specifies the group used to store data. If you do not specify newgroup, SYSGEN stores any configuration changes in the base group by default.

If the group specified by newgroup already exists, SYSGEN asks, at keep time, whether or not it should overwrite that group with new information. At keep time, if the user does a KEEP with no parameters, SYSGEN keeps the current base group unless newgroup was specified, in which case the group given is used. More information on using the KEEP command is provided later in this chapter.

The inputfile parameter specifies the file designator of the file for command input. The formal file designator is SYSGIN. The default is $STDINX.

The outputfile parameter specifies the file designator of the file for SYSGEN output. The formal file designator is SYSGOUT. The default is $STDLIST.

When using parameters with the SYSGEN command, place them immediately following the command: 

   :SYSGEN[basegroup][,newgroup][,inputfile][,outputfile]
When using parameters with RUN SYSGEN.PUB.SYS, you must specify them in the phrase INFO=" ": 

   RUN SYSGEN.PUB.SYS;INFO=
   "[basegroup][,newgroup][,inputfile][,outputfile]"
Example 4-1 illustrates activating SYSGEN's global module. Activate the SYSGEN global module by entering the command SYSGEN or by entering RUN SYSGEN.PUB.SYS.
