As I pointed out, if he's using an older version he might find what he wants in the release notes of the newer version, or, as I suggested (don't know if this is available) the vendor could make some "running total" list of fixes which later show up in the release notes---this obviously exists as an internal list. > He wants a facility to enable him to determine *beforehand* whether a > certain bug report is superfluous. Right. No-one is talking about an EXHAUSTIVE list (that's probably impossible). Assume such a release-notes type list exists. Normally, one changes the code in steps and recompiles after each step. :-| If I see a problem, I know what I have changed. (And on VMS I have all the old versions; I don't see how one can do productive software development without such a system!) Suppose it has something to do with a defined assignment involving a user-defined type containing pointers to arrays. I can then search this list for these "key words" and see if I see something which might be my bug.
