;New with patch 229
;DELPTR will go thru all the files that point to a given file and
;delete any pointer to a set of deleted entries.
;FILE is the file number that the entries are being deleted from.
;DELRT is the closed root of an array of IEN values being deleted.
;SKIP is an array of files to skip from deleting
