Basically, we were going to skip this slide but I asked Tamar to stop on this problem as it sounded interesting. It was very quick so I don't really remember if she showed this tip in action or not. It should be in her book too.

Hopefully she'll answer herself here later on.

>In earlier versions of VFP I got burned with some very hard-to-track bugs when using RECNO() in SELECTs. There were significant SQL engine enhancements in VFP9; maybe it's now safe to use it that way. However, VFP9 also supports more complex queries in general, and without a lot of testing, how can we be assured that RECNO() will work as expected in these scenarios?

That's for sure. In SQL Server you may use NextID trick, though I don't recall at the moment and need to search.
