Many CA EPIC for z/VSE features rely upon DTF information that is automatically provided by the LIOCS access methods. CA EPIC for z/VSE also relies upon the standard open/close/end-of-extent/end-of-reel processing used by LIOCS. Because all sort programs use PIOCS to process data, the functionality of CA EPIC for z/VSE features varies depending upon which sort product is in use.
The following table details the operation of specific CA EPIC for z/VSE features when used with the sort programs. Its information is based upon DFSORT release 3.4, CA-SORT release 9.0, and SYNCSORT release 2.2c. These considerations apply only to datasets that are opened directly by the respective sort program. In addition:
When executing sort using the VSE EXEC statement, these considerations apply to SORTIN, SORTOUT and SORTWK.
When the sort is called internally by another program, these considerations usually apply only to SORTWK.
When executing TSIDSRT, these considerations apply only to SORTIN and SORTWK.
