Thanks to all of you for your answers. Of course, it does not seem to be as easy as "some" are saying. My investigation is getting more precise. I am sure I will have more questions soon.

Good day to all of you Laure ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
