To Delete Keys

You can use a KGUP control statement to remove a key or a range of keys from the CKDS. This statement shows the syntax when you delete keys from the CKDS:
   DELETE  LABEL(label) or RANGE(start-label,end-label)
   TYPE(data,exporter,importer,ipinenc,mac,macver,
   null,opinenc,pingen, or pinver)
