1. Which storage space is assigned to the Region parameter coded in either job or exec, like whether is virtual or real?

2. If this parameter is not coded, then what is the default space allocated.
How is this space determined?

hi frnd,

A REGION parameter to specify how much virtual storage the step needs.

Some says:
If no REGION parameter is specified, the system uses an installation default specified at JES initialization.

Some Says:
If no REGION parameter is specified, the system uses 0M where 0-is the whole space which the system holds at that time.


i had got two answers... analyze and let me know the right one.

Hi there

your first answer was right If region parameter is not specified, then the system uses an installation default specified at JES initialization.

When you specify 0M ,,then it takes whole space.
