Using the DLET call

The DLET call is a request to delete a path of segments, not a request to release the DASD space used by a segment.

Delete rules are needed when a segment is involved in a logical relationship, because that segment belongs to two paths: a physical and a logical path. The selection of the delete rules for the logical child and its logical and physical parent (or two logical parents if physical pairing is used) determines whether one or two DLET calls are necessary to delete the two access paths.
