REGION:

Specifies the address space required to run a job step within the job.

Following is the syntax:

REGION=nK | nM

Here, region can be specified as nK or nM where n is a number, K is kilobyte and M is Megabyte.

When REGION = 0K or 0M, largest address space is provided for execution.In critical applications, coding of 0K or 0M is prohibited to avoid wasting the address space.
