These are theparameters:v NAME specifies the name of the page space, SYS1.PAGE2.vvCYLINDERS specifies that the page space is to occupy 10 cylinders. The pagespaces are never extended.VOLUMES specifies that the page space is to reside on volume VSER05.The page space defaults to NOSWAP.Define a SWAP Page Space: Example 2//DEFPGSP2 JOB ...//STEP1 EXEC PGM=IDCAMS//SYSPRINT DD SYSOUT=A//SYSIN DD *DEFINE PAGESPACE -(NAME(SYS1.PAGE1) -CYLINDERS(10) -VOLUMES(VSER05) -SWAP/*The DEFINE PAGESPACE command defines a page space.
