Version (MQLONG)

The value must be one of the following:

MQCNO_VERSION_1
Version-1 connect-options structure.
MQCNO_VERSION_2
Version-2 connect-options structure.
MQCNO_VERSION_3
Version-3 connect-options structure.
MQCNO_VERSION_4
Version-4 connect-options structure.
MQCNO_VERSION_5
Version-5 connect-options structure.

This version of the MQCNO structure extends MQCNO_VERSION_3 on z/OS(R), and MQCNO_VERSION_4 on all other platforms.

Fields that exist only in the more-recent versions of the structure are identified as such in the descriptions of the fields. The following constant specifies the version number of the current version:

MQCNO_CURRENT_VERSION
Current version of connect-options structure.

This is always an input field. The initial value of this field is MQCNO_VERSION_1.
