The following error might occur when using ODS on the z/OS operating system after the application of hot fix E9BC53 or E9BC70:

Error:  No logical assign for fileref.

The fileref in the error message refers to the DDname allocated in the JCL for the output file being used by ODS.

The problem will occur when using mutiple ODS statements to write multiple members to the same PDSE. The first write to the output file will work correctly. However, all subsequent attempts will generate the error message shown above.

Since the problem only occurs when the fileref is defined in the JCL, to circumvent the problem, replace the DDname in the JCL with a FILENAME statement in the SAS code.
