The IBM CICS Transaction Server for z/OS supports channels and containers for
EXEC CICS LINK. In this respect CICS containers can be
considered as named COMMAREAs without the 32 KB limit.
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 NTCICSP macro parameter CNTCALL is set to
ON, 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.
