Adding vertexes with UV coords

>Is the help file wrong or am I missing something here?

You are reading the textfile wrong.

http://www.blitzbasic.co.nz/b3ddocs/command.php?name=AddVertex&ref=comments

This is the same helpfile as the docs.

The top left of an image has the uv coordinates 0,0. 
The top right has coordinates 1,0 
The bottom right is 1,1. 
The bottom left 0,1.
