DEFINE ALIAS (NAME(SYS2) RELATE(MASTCAT.SYSTEM2))
       DEFINE PAGESPACE -
              (NAME(SYS2.PAGE2) -
              CYLINDERS(10) -
              VOLUMES(VSER05)
         ALTER SYS2.PAGE2 NEWNAME(SYS1.PAGE2) CATALOG(MASTCAT.SYSTEM2)

Job control language statement:

VOLUME DD describes the volume on which the data space is to be defined. .

The DEFINE ALIAS command defines an alias pointing to a target catalog in which the pagespace is to be defined.

The DEFINE PAGESPACE command defines a page space. These are the parameters:

NAME specifies the name of the page space, SYS2.PAGE2.
CYLINDERS specifies that the page space is to occupy 10 cylinders. The page spaces are never extended.
VOLUMES specifies that the page space is to reside on volume VSER05.

The pagespace is created in catalog MASTCAT.SYSTEM2. The ALTER commands rename the pagespace to a SYS1 high-level qualifier in the target catalog.
