Yes.

In fact this is even better!

        use WHERE RecID = 0

Mmm, only if they are AFTER all fields in file.

IF this is YOUR calculations in RB code, then Valentina's Import of course
cannot calulate them. And you can not do this using first cursor, because
Valentina will not return control to you until it finish Import.

So you must calculate them later after import.

As data

Agree.

I will check this.

In fact no doc team yet. I have write it self.

My dream is to get one or 2 helpers on docs.
There is chances that I will get them for 2.0 ver.
