Not that I know of. SuperCE seems to only be able to produce listings of the differences and "update" or "revision" files that have additional data added to them (control cards and/or markings on "changed" lines, etc.). We have always had to use third-party products for straight data compares of non-text files. The Comparex and Insync products both do this quite well, but of course they cost your shop more money if you don't already have them. There are other vendors out there with equivalent file compare products, but those are the only two with which I have had personal experience. There is always the option to write your own unique compare utility for your particular data files, but that also costs time and effort which are also additional costs for your shop, not to mention the need to maintain that code in the future as file formats change. It is possible to write code (e.g., I would do it in Rexx) to analyze an "update" file output from SuperCE to select the record numbers that are different in each file and then read the input files to extract those record numbers from the original data files, but I haven't had to do such a project myself. I also found the SuperCE limitation of not being able to show differences beyond position 176 of the input files to be absurdly limiting, especially when data records can be thousands of bytes long. These limitations have always led me to believe that SuperCE and its predecessors were only ever intended to process plain text files, primarily source code and documentation text files, not non-text data files, but that is just my opinion. Mind you, SuperCE does do a very good job of detecting text file changes.
