ADDRSPC parameter is used to indicate storage required by the system.

The storage can be virtual (not real pagable) or central (real storage and nonpageable).

ADDRSPC parameter is an optional parameter.


Syntax:

ADDRSPC= {VIRT/REAL}

VIRT Specifies the request is for virtual storage.

The system can page the job.
REAL Specifies the request is for real/central storage.

The system cannot page the job.

Each step of the job must place on the central storage.

Default and overrides:


If no ADDRSPC parameter is specified, the default storage requested is VIRT.

The JOB statement ADDRSPC parameter applies to each step of the JOB.

If ADDRSPC parameter specifies at JOB level and EXEC level, JOB level ADDRSPC overrides any EXEC statement ADDRSPC parameter.

Code EXEC statement ADDRSPC parameter when no ADDRSPC parameter specified at JOB level.


Example 1:

//MTHEXMP1 JOB (META007),'PAWAN Y', REGION=10K

This JOB statement indicates that ADDRSPC not specified. As per default value, ADDRSPC parameter requests virtual storage. So the space available to the job is 10K virtual storage.


Example 2:

//MTHEXMP2 JOB (META007),'PAWAN Y', ADDRSPC=REAL, REGION=10K

This JOB statement indicates that ADDRSPC specified as REAL. ADDRSPC parameter requests central storage. So the space available to the job is 10K central storage.


Example 3:

//MTHEXMP3 JOB (META007),'PAWAN Y', ADDRSPC=REAL

This JOB statement indicates that ADDRSPC specified as REAL. ADDRSPC parameter requests central storage. The space available to the job is the installation-specified default central storage.


Example 4:

//MTHEXMP4 JOB (META007),'PAWAN Y'

This JOB statement indicates that ADDRSPC not specified. As per default value, ADDRSPC parameter requests virtual storage. The space available to the job is the installation-specified default virtual storage.
