Field Extract and Update Facility

The Application Interface can extract and/or update fields attached to an ACID. All user‑defined fields can be extracted and/or updated, as well as many of the fields in the FDT.

Predefined fields (like TSO and CICS) are not valid for TSSAI processing.

To extract field data, the User ACID must have the DUFXTR attribute; the DUFUPD attribute is required to update field data.
