Bill,
Step 1 : Get Listcat information for the GDG Base
Step 2 : parse the Listcat information for the migrated generations and
generate HRECALL commands using DFSORT
Step3 : Run the commands from step 2
//***************************************************************
//* GET THE LIST OF DATASETS NAMES USING LISTCAT ON GDG BASE *
