Saving configuration changes is a two-step process. After making the changes in any of the configurators, you must hold those changes before exiting the configurator to continue your work.

Use the HOLD command to temporarily hold the changes made in a configurator. Holding changes allows you to move among configurators or between a configurator and the global module without losing changes.

Refer to the sections on the IO, LOG, MISC, or SYSFILE configurators for information on using HOLD within each configurator.

The KEEP command (abbreviated KE or K) saves (stores to disk files) changes held from any of the SYSGEN configurators.

KEEP has the syntax: 

   KEEP     [ [NAME=]groupname ]
Groupname may be eight characters or fewer and must begin with an alphabetic character.

SYSGEN keeps track of the current configuration group, whether it is the default group with which you booted the system, a group specified by the basegroup parameter on the initial SYSGEN command line, or a group switched to by the BASEGROUP global configurator command. If you do not specify a basegroup with the KEEP command and did not specify a group with the newgroup parameter on the initial SYSGEN command line, SYSGEN uses the current working base group (either the default or the one set by a method listed above) to save the configuration changes.

The KEEP command can be used to save configuration changes to a group other than the current working group. In addition, if the desired group does not already exist, the KEEP command creates it and then saves the configuration changes to it. All groups are saved in the SYS account.

To keep changes to a group other than the current working configuration group, enter the KEEP command and a new group name: 

   sysgen>KEEP NEWCONFG   (Sample name only)
If changes are being saved to a group that has existing configuration files, SYSGEN asks if that group should be overwritten: 

   sysgen>KEEP FEUDAL

   purge old configuration (yes/no) ?NO

   ** configuration files not saved **
Answering NO cancels the command.

If insufficient space exists on the main system disk to accommodate the creation of a new configuration group, SYSGEN issues a message indicating this. SYSGEN then terminates, losing the temporary files and the changes.
