A module could not be found in the libraries in the linklist or there was a failure in trying to load the module that was found.
The system continues processing. The system will not call a diagnostic exit during tracing of partitioned data set directory entries (PDSE) or other DFP products supported by the PDSE function.
Notify the system programmer.
Ensure that the diagnostic exit routine is linked as authorized (AC=1), it is placed in an authorized library, and that library is in the LINKLIST.
