LCD code makes no sense

Here is a page that has code to run the LCD with PBP. I have no experince with LCDOUT so looking for decent tutorials (aren't any really).

Huh ? !

It has a lot of references in comments to the LCD connections but nothing in the main code. ? I haven't tested it because it doesn't make any sense.
What if I wanted to use different ports etc.

Where is there a decent tutorial on LCDOUT ? The Picbasic manual also is rather vague.
