The below JCL you can use to delete GDG base cluster. The interesting point is if you delete the GDG base, automatically it deletes all the versions.
Sample JCL
//Step1 EXEC PGM=IDCAMS //SYSIN DD * DELETE 'XXXX.XXXX.XXXX.XXX' GDG FORCE /*
Alternative JCL Example
(or) if we want to delete migrated-GDGS, use the following syntax.
//Step1 EXEC PGM=IDCAMS //SYSIN DD * HDELETE 'XXXX.XXXX.XXXX.XXX' GDG FORCE /*
Notes: To delete VSAM clusters, give CLUSTER in place of GDG.
