>I've already done it on someone's project, when converting from 7 to 9, and only had to hunt "group by" in code references, and had to have a ready search/replace on "if _tally=0" to replace with "if isnull()", where I'd only have to insert the name of a field of the resulting cursor, or name of the array. Once you get the hang of it, you can do about twenty or thirty of those in an hour. I know it takes only about ten seconds to do, the rest of the time is checking that it's right.

Thanks! that is very reassuring.
