MEMLIMIT={nnnnnM} {nnnnnG} {nnnnnT} {nnnnnP} {NOLIMIT}

2.Subparameter Definition

nnnnnM
nnnnnG
nnnnnT
nnnnnP
Specifies a value to be used as the limit on the total number of usable virtual pages above the bar in a single address space. The value may be expressed in megabytes (M), gigabytes (G), terabytes (T), or petabytes (P). nnnnn may be a value from 0 to 99999.

NOLIMIT
Specifies that there is no limit on the virtual pages to be used above the bar.

3.Defaults
If no MEMLIMIT parameter is specified, the default is the value defined to SMF.

4.Overrides
The JOB statement MEMLIMIT parameter applies to all steps of the job and overrides any EXEC statement MEMLIMIT parameter. If MEMLIMIT is not specified, SMF provides a default value. The IEFUSI installation exit can override any JCL- or SMF-supplied value.

5.Example of the MEMLIMIT Parameter

//STEPA EXEC PGM=ADDER,MEMLIMIT=10000M

This job step specifies a limit of 10000 megabytes of usable virtual pages above the bar, depending on other job and installation factors.
