On the documentation question, that seems like a perfect case for you to submit an RCF for the manual. I don't agree, though, that the non-standard override is valid. Utility code should ALWAYS respect the wishes of the programmer, including DCB overrides. After all, we're paid to know what we're doing, right? :) As a separate issue, IMHO SUPERC is *not* an "awesome facility", except perhaps for report/text/source code processing. For structured data file comparison it is nearly unusable. Any byte beyond 176 (IIRC) is never displayed in the output listing, so if you have a difference beyond byte 176 you will never see that difference. Not to mention a complete lack of masking facilities, multi-record-format facilities, etc. IOW, it's convenient (and sometimes superior, I must admit) for comparing free-form text files or reports, but not good for structured record comparisons. As it is, SUPERC is just trying to be the equivalent of the *ix "diff" utility for z/OS, and it doesn't even support the "diff3" paradigm. A truly "super" comparison utility would be much more complete.
