MVS SYSTEM CODES -S513

An error occurred in opening two data sets on the same magnetic tape volume.
This only works with SYSOUT data sets.

1. Two data sets were assigned to the same device.
2. An open was issued for a second data set on the same tape device before the first one was closed.
1. Verify that the JCL is correct
2. Check the file usage in the program.
