Description

The intersystem program provides services for CICS system code that wants to use intersystem or interregion (IRC) function requests:
RECEIVE
Is invoked when DFHCRNP gets input data as a result of a ‘switch first’ SVC request.
IOR
The IRC input/output routine. This interfaces with the IRC SVC in order to send data to the other end of the connection, or await data from there.
GETDATA
Is used to fetch input data into a TIOA.
DISCONNECT
Disconnects a given IRC link.
STOP
Quiesces interregion activity, either for connections to a given system, or for the whole of IRC.
LOGOFF
Issues a logoff request to the IRC SVC. This completes IRC activity for this CICS system.
OPERATIVE
Allows connections to be made to a given system.
RECABRT
processes input abend FMHs (FMH07).
