Funny that, I based my head against a wall trying exactly that syntax, I 
eventually found some old gambas code on the web that worked.

But... just typed it in again, and it works. Dunno......... maybe I didn't 
capitalise it or something.

Anway, thanks.

Like everything else in gambas, blindingly simple if you know.
