The input data set block size is incompatible with the output data set block size.
For fixed length records, the size of each block must be a multiple of the logical record length.
For variable length records the output block size must be equal to or greater than the input logical record length.
For undefined length records the output block size must be equal to or greater than the input block size.
The severity is 8.
For RECFM=U data sets, the copy operation continues. For all other RECFM, the copy operation ends.
If the error recurs and the program is not in error, look at the messages in the job log for more information. Search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Provide the JCL and all printed output and output data sets related to the problem.
Respecify the output block size to allow this member to be properly copied. Copying a larger block size to a small block size can create "fat" blocks, which cause I/O errors when other programs try to read them. Use COPYMOD instead of COPY to reblock load modules.
