Set the ADSDescriptor field as follows:

• If we are not using ADS descriptors, set the field to MQCADSD_NONE.
• If we are using ADS descriptors with the same CCSID in each environment, set the field to the sum of MQCADSD_SEND and MQCADSD_RECV.
• If we are using ADS descriptors with different CCSIDs in each environment, set the field to the sum of MQCADSD_SEND, MQCADSD_RECV, and MQCADSD_MSGFORMAT.

This is a request field used only for 3270 transactions. The initial value of this field is MQCADSD_NONE.
