I changed it, some other problem occured.
1. How to compare a BoolT column to a True? "t!c .<>. True" could not work.
2. What shoud I use after "!"? Like table!col, recordset!col, what is col?
Thanks.

Hi, I am learning it following the very few documents on its site. Well, I failed, with the import modules, I still cannot compile it. The error is on "T.*".
