Make Compare More Accurate

The compare facility is a simple text compare. It easily gets confused when changes to source are too complex. It would be nice if the source compare had at least a little language specific intelligence. In RPG for instance the compare routines could recognize complete procedures and subroutines by name, and if there are extra subroutines or procedures recognize that fact, and use that to improve the comparison. Right now I am looking at a module source for a service program that has some missing procedures, and some extra procedures on one side, and the text compare is completely confused, failing to match procedures that exist in both sources in the vicinity of the differences. It does eventually get back on track, but a little intelligence that knows that a procedure or subroutine is an independent entity to be compared on it's own would make the compare more accurate.

By the way, in my current case PDM option 54 correctly identifies the differences while the RDi Text Compare includes things as differences that are actually the same.

    Thank you for taking the time to submit your request. After careful consideration, we know that we cannot deliver your requested enhancement in the near term, so it is being declined. However, your request does align with the future strategy of our product and we believe it may have future value, so we will add it to an internal list for us to keep in mind for the future.

    Speaking of language specific intelligence you should also see the RFE on syntax highlighting and outline in the compare view. I's a pity (if not a shame) that CODE/400 is still the better tool for comparison. http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=81749

    Although the theme of this request is consistent with our business strategy, it is not committed to the release that is currently under development.

    I have added a screenshot to illustrate the issue.

    Attachment (Description): This screen shot shows some source that has been compared using RDi's Text Compare utility. On the left is a procedure UserIsConnectedInternally() which actually exists in both source files, and is the same in both. On the right is a procedure SetUids() which only exists in the source file on the right. As you can see, UserIsConnectedInternally() is incorrectly included in the difference. Note that option 54 from PDM does the compare correctly.
