See the addrspc parameter specify wheter the job is using virtual memory or real memory at the time executing but deafultly its virtual memory.

Region paramater indicates the job is using some amount memory for execute the job if job needs more than what we have spicefied in REGION parametr than its gives s804 ERROR OR S822 ERROR.

PLEASE REPLY TO MY ID

Hi

ADDRSPC: this parameter specifies whether your job should use the Virtual memory or the Real memory when executing.

Advantage of Virtual memory is the Job can be paged. Virtual is Default.

Region:- Region parameter allocates the specified memory in the Real storage or Virtual storage as mentioned in the ADDRSPC parameter.

If they are coded in the EXEC statement then they are applicable only for that step.

If coded both on job and exec then Job overrides Exec.
