BIM-EPIC Sort Interface (TSIDSRT)
The BIM-EPIC sort interface program (TSIDSRT) addresses all the considerations described
above, and usually requires no JCL changes except the phase name on the EXEC statement.
TSIDSRT does the following:
1. Reads the sort control statements and modifies the input BLKSIZE to match the block size
in the BIM-EPIC Catalog.
2. Assigns tape datasets to a "dummy" tape device and opens disk datasets to satisfy pre-open
checking.
3. Calls the sort program.
4. Uses the sort program's E35 exit routine to write the SORTOUT dataset. This allows
access to DTF information necessary to support such BIM-EPIC options as disk dataset
truncation, reblocking, and logging of block size, record size and record count.
5. Closes SORTWK datasets to enable them to be deleted.
Unless using a sort program that has a direct interface to BIM-EPIC (e.g. SYNCSORT), the
recommended method of using sort programs with BIM-EPIC-controlled datasets is to use
TSIDSRT. BIM-EPIC special option EPS083 provides for automatically changing 'SORT' to
'TSIDSRT' on EXEC statements.
