After the SCIP exit is driven, the application program
checks the RPLVACS bit in the read-only RPL supplied in the parameter
list to determine if the session is an LU 6.2 session. If this bit
is set on, the application program should respond to the session request
with one of the following macroinstructions:
- APPCCMD CONTROL=OPRCNTL, QUALIFY=ACTSESS to accept new sessions
- APPCCMD CONTROL=OPRCNTL, QUALIFY=DACTSESS to reject new sessions
For more details about the SCIP exit, see page SCIP.
When the application program issues the APPCCMD CONTROL=OPRCNTL,
QUALIFY=ACTSESS or APPCCMD CONTROL=OPRCNTL, QUALIFY=DACTSESS macroinstruction,
it must include the communication identifier (CID) of the session.
The CID is found in the parameter list that VTAM® supplies in register 1 when the exit is
scheduled. The location of the CID is shown in
Table 1.

The ARG field on the APPCCMD macroinstruction is set to the
CID when the macroinstruction is issued.
