Answer: You reference an entire GDG by not soecifying a version number on the end. To delete all of the generations of a GDG you just run an IEFBR14 step referencing the GDG base name and disp=old,delete. For example if your GDG is called PROD.MYGDG.FILE then you can use the following JCL.
//S1 EXEC PGM=IEFBR14
//F1 DD DSN=PROD.MYGDG.FILE,DISP=(OLD,DELETE)
You only need to use IDCAMS if you want to delete the GDG base itself.
