The ADDRSPC parameter is used to specify the storage required by the system.
Some important points about ADDRSPC parameter are as follows.
- It is an optional parameter.
- The storage can be virtual or central.
- The REGION parameter requests the storage for an individual step.
- ADDRSPC prevents paging.
- ADDRSPC=VIRT is used for paging.
- Once ADDRSPC is set to REAL(ADDRSPC=REAL), the step would be locked into real storage, when executed.
- Its effect is adverse to the performance of the system.
