In this example, a generation data group base catalog entry, GDG01, is deleted from the catalog. The generation data sets associated with GDG01 remain unaffected in the VTOC.

//DELETXX   JOB   ...
//STEP1     EXEC  PGM=IDCAMS
//SYSPRINT  DD    SYSOUT=A
           DELETE -
           GDG01 -
           GENERATIONDATAGROUP -
           RECOVERY
/*

The DELETE command removes the GDG base catalog entry from the catalog. Its parameters are:

• GDG01 is the name of the GDG base entry.
• GENERATIONDATAGROUP specifies the type of entry being deleted. VSAM verifies that GDG01 is a GDG entry, then deletes it. If GDG01 is not a GDG entry, VSAM issues a message and does not delete it.
• RECOVERY specifies that only the GDG base entry name in the catalog is deleted. Its associated generation data sets remain intact in the VTOC.
