      FUNCTION = The DFHTCAPS copybook declares the structure
                 for the TASK CONTROL AREA (TCA). The TCA is the
                 primary control block used by CICS to represent a
                 transaction within AP domain.
                 The TCA is a single area of storage described
                 by structure DFHUSTCA. However, it is also
                 possible to access the TCA as two separate
                 structures, DFHUSTCA (User area) and DFHTCADY
                 (System area). Field TCASYAA in DFHUSTCA
                 contains the address of DFHTCADY, for this purpose.
                 When reading code that deals with TCA fields, it is
                 important to know which method of access is used.

1	HEX	00	TCADLNR	Normal Response
1	HEX	08	TCADLINV	Invalid Request (Reason in TCADLTR)
1	HEX	0C	TCADLNOP	Not Open (Reason in TCADLTR)
TCADLTR may contain the following response codes:- When Normal Response - TCADLRC=TCADLNR TCADLTR will also contain TCADLNR to indicate Normal Response When Invalid Request - TCADLRC=TCADLINV
