>I also think so, and I believe it works relatively fine with small tables. One of my tables had more than 5 million records and a size of around 100MB, and it crashed all the time. I also had smaller tables which did not cause any crashes, but phDbase did not find all the matching records, and this was repeatable. So I gave up, and created my own functions which have some of the phDbase features I needed.

I remember now that Michel reported similar problems with big tables and had to split them into smaller once.
