The diskette reader is ended.
If the number of associated data sets to be processed (PARM= value) or the number of directory entry blocks allocated to the SYSUT3 file were modified via the START command, insure that the values were reasonable. The number of associated data sets should not be so large as to leave no virtual storage for the STOW function. The number of directory entry blocks should be 1 + (number of ADS ÷ 20). If these values were reasonable, the error was caused by an I/O error in the SYSUT3 file. Correct the cause of the error if possible, and start the diskette reader again to run the job stream.
Correct the number of associated data sets and number of directory entry blocks specified in the JCL. Then rerun the diskette reader.
