OOhh right !
I think I used Ctrl + C - Ctrl + V a little bit too much

I had copied the syntax of "OpenTextFile" actually..
var Mefile = ObjSys.OpenTextFile(path, [ Mode [, Create? [, Format]]])
The "2" was supposed to be the mode (ForWriting) but I guess I just don't need it.
Thx
(And sorry about the language... I'm doing my best

)
