Exit routine task association

The associated task is the ACB task when the following exit routines are dispatched:

ACB exit routines–NSEXIT, LOGON, LOSTERM, RELREQ, TPEND
SCIP exit routine (either ACB or NIB specified) for BIND and UNBIND processing
ACB-specified session exit routines–DFASY, RESP, SCIP
NIB-specified session exit routines if authorized path OPNDST or OPNSEC was not used to establish the session–DFASY, RESP, SCIP
RPL exit routine for an RPL-based macroinstruction that does not use authorized path (additionally for communication macroinstructions, an authorized path OPNDST or OPNSEC macroinstruction was not used to establish the session).

The associated task is the session task when the following exit routines are dispatched:

NIB-specified session exit routines if authorized path OPNDST or OPNSEC was used to establish the session–DFASY, RESP, SCIP (for other than BIND and UNBIND processing)
RPL exit routine for an RPL-based communication macroinstruction if authorized path OPNDST or OPNSEC was used to establish the session
RPL exit routine for an RPL-based communication macroinstruction that does use authorized path.

The associated task is the issuing task when the following exit routine is dispatched:

RPL exit routine for an RPL-based non-communication macroinstruction that does use authorized path.

The associated task for a LERAD or SYNAD exit routine is the task associated with the corresponding RPL-based or CHECK macroinstruction.

The associated task for a RECEIVE OPTCD=ANY RPL exit routine can be the ACB task or the session task, depending on when the exit routine is scheduled. For LERAD or SYNAD exit routines invoked because of RECEIVE OPTCD=ANY, the associated task can be the issuing task, the ACB task, or the session task.
