Sorting Specifics
Many BIM-EPIC features rely on DTF information that is automatically
provided by the Logical Input Output Control Systems (LIOCS) access
methods. BIM-EPIC also relies on the standard open, close,
end-of-extent, and end-of-reel processing used by LIOCS. Not all sort
programs use LIOCS to process data so the functionality of the
BIM-EPIC features can vary depending on which sort product is used.
The following details how specific BIM-EPIC features perform when
used with several sort programs. These considerations apply when the
sort program is directly executed using the VSE EXEC statement and
then only to datasets that are opened directly by the sort program. These
considerations do not apply to datasets that may be opened by
user-written sort exits. The following characteristics apply to the
SORTWK file when the sort program is invoked by TSIDSRT or by
another program internally.
