With CICS Transaction Server Version 3.1, IBM introduced channels and
containers for EXEC CICS LINK. In this respect CICS
containers can be considered as named COMMAREAs without the 32 KB limit.
The Natural CICS interface supports CICS containers in two ways:
Via a special SET
CONTROL 'P=CC', the
CALL statement parameter
data is passed in a container.
When the NCIPARM system
generation parameter CNTCALL is set to
YES, a %P=C
CALL automatically uses a CICS container rather than a CICS
COMMAREA, when the parameter data passed with the
CALL statement exceeds
32 KB.
In both cases, the default container name is NCI-COMMAREA
unless a container name is defined explicitly via application programming
interface USR4204N prior to the "real"
CALL statement.
