Ok, So I have posted questions a few times, but now I will make it interesting so I the question is better communicated, hopefully resulting in some quicker solution than to spend alot of time rewriting code that is so tempting to use as it is existing..
Abstract: People visiting art galleries often talk quetly. On the wall in a darkened portion of a gallery-room, a 6' x 4' apparently blank canvas is hanging on the wall.. Periodically a small snip of words recorded in the room will be written out in my handwriting which seems to magically begin glowing on the canvas. The more communication in the space, the more words will be all over the painting.
How it works: As hidden directional wireless microphones pick up random snipits of conversation, speech to text software outputs a text file every few minutes. This text file is then loaded with a macro into a wordprocessor, formated for the right size, and then output into an HPGL language file in a shared network on an old windows98 machine running QBASIC software which I have adapted from luberth. Instead of being carved or plotted, the 'Z' activates a powerfull UV LED which exposes a UV-sensitive polymer-paint, creating a temporary plot. Ideally I will use a TTF font of my own hand writing.

I have the machine working and drawing. The QBASIC software will be very easy to add a timer, so i just looks in a directory for a file name every X amount of time..
Pictures! and then finally the question. Sorry for writing a short novel!
Question This thing needs HPGL files to run. I have a sample HPGL file from Luberth's web site (http://www.luberth.com/plotter/qbplot01.zip) I am using the simpler, seperate QBplot00.bas QBASIC file. How can I figure out the parameters of the original HPGL file... Language version? Links to sites with technical specifications? I havent been able to find them.? Someone know about this?
In the photos the fabric material which is to be coated with UV-sensitive paint is not present. Just imagine the XY plotter behind a thin translucent fabric barrier.
Thanks anyone who even bothers to read this! Hopefully someone has some hpgl experience! I have asked a few times.. I am sorry.. And, Thank you!
