I found this PHP code that might be of use. Currently it is set up to highlight PHP code sections (i.e. |php||/php|) in a C like fasion. We might be able to modify it so it handles |code||/code| sections and highlights itin a Pascal fashion.

P.S. I also found this one for VB style highlighting. Now if I could just find one for Pascal!!!!

P.P.S. Maybe I'll sit down and see if I can convert it myself.
