I have usually found that the SuperC utility (ASMFSUPC actually, the HLASM Toolkit enhanced version) does a very creditable job of finding differences in text or report files, and is quite useful in regression testing batch application changes.
However, I just discovered that the compare process can "lose its place" comparing text files with a significant number of changes. I have an application change that inserts an additional 4 lines of text every 6ith line of the original text, with the differences and inserts scattered over all the sections of a report. There are 115,400 new records and 115,400 changed lines in total, arranged such that there are four changed lines immediately preceding each of the sets of four inserted lines. The original file has 268,716 lines and the new file has 389,323 lines. There are heading lines for each page as well, so I used the DPLINE option to tell SuperC to ignore the header lines and the entirely blank lines. However, after 13,467 lines of the original file and 20,154 lines of the new file, SuperC seems to stop recognizing changed/inserted lines in groups and starts reporting huge globs of deletes and inserts (6,439 deletes followed by 10,778 inserts the first time it lost its place). Has anyone else seen this behavior? Is there anything I can do to help SuperC "keep its place" and report the actual changes instead of globs of inserts and deletes?
