Specifying the Parameters: SYSIN Statements

Specify as many of the parameters as possible with SYSIN statements to manage multiple regions easily.

The REGION parameter is positional and must be specified in the PARM= statement of the cross-memory task JCL. Specify the following parameters in the PARM= statement:

SUBSYS=
SARAPPL=
XMS=

You can specify the rest of the parameters with SYSIN DD statements. If you place the SYSIN statements in a PDS member, you can alter the parameters without shutting down the cross-memory region.

Note: The parameters do not take effect until the next time the region is shut down and restarted.
