Offline EXTEND command

The scenarios in this section show how to use the EXTEND command in conjunction with key related keywords and subcommands.

Before executing the control statement, you must ensure that adequate space is present on the primary volume of the target area data set to accommodate the request for additional UOWs. If the necessary space is not present, allocate volumes to the area data set by using IDCAMS ALTER ADDVOLUME.
