That should exist as a general purpose interface to "the other side of a
DDNAME".
Imagine being able to connect a Pipeline to SORTIN and SORTOUT to a Pipeline
independent of the sort routine (DFSORT , SYNCSORT, ...) as easily as in UNIX:
502 $ ls -li | sort -unk1,1 | wc # Count unique i-numbers.
997 10232 78714
( I recall in the documentation for Pipelines SORT a statement that large data
sets are better handled by an external SORT routine.)
Such a facility should not be specific to SORT, but should support any classical
utility that has an input file and an output file.
