I'm not sure that concatenation will work for files with different lrecls. . . As the in-put has multiple lrecls defined as FB, i suspect there would be an abend when the run did not contain all files with the same lrecl.
Later, the Ist o/p file is used in some processing.
Even if concatenation would work, i still am confused about how the different-format data would be used in a common file
Now, there is a new bit to the requirement to determine if a particular file was copied successfully (not something typically done by cobol code). . . .
