Error message

MULTIPLE LREC BUFFER MODIFICATION IS NOT ALLOWED

Explanation

An application program issued one of the following APIs to modify the z/TPFDF multiple LREC buffer:
  • A DBMBUF macro
  • A dfmbuf function
  • A DBRED macro with the MULTI parameter specified
  • A dfred_multi function
However, the z/TPFDF multiple LREC buffer is in read-only mode because the buffer address is published.

System action

Control returns to the application program with the SW00RT4 field set to 2 for the DBRED macro and the dfred_multi function, or with the buffer return field set to 128 for the DBMBUF macro and the dfmbuf function.

User response

Modify the application program to work with a buffer that is not in read-only mode.
