When using SORT (either DFSORT or SYNCSORT) to select a relatively small sample of records by (a) particular key value(s) from a *very large* sequential file, when one knows in advance that the "key values" used to select the desired sample records are in sorted order in the input file, is there any way to tell SORT the following:
"After this key (these keys) in the input file are greater than any key selection value I gave you, stop reading the input, because it is sorted by this key (these keys) and I know you can't find any more after that point in the input file." The object of telling SORT this is not to read any more input records than is absolutely necessary to make the desired selection. It would be very helpful in performance-constrained LPAR's.
