StrucId (MQCHAR4)

The value must be:

MQCIH_STRUC_ID
Identifier for CICS(R) information header structure.

For the C programming language, the constant MQCIH_STRUC_ID_ARRAY is also defined; this has the same value as MQCIH_STRUC_ID, but is an array of characters instead of a string.

This is a request field. The initial value of this field is MQCIH_STRUC_ID.
