Hi Khadga,

I had no clue how to use the batch command. Thanks for the info ;)

I created ~/.maxima. I put maxima-init.mac and texmacs.mac there. Then in 
maxima-init.mac I have the single statement (load "texmacs.mac"). This keeps 
me from mucking around with files in /usr.

The problem is the ^B and ^E strings you see in the maxima code I posted. 
Those are control characters. A single character each, not the two characters 
^ and B. I should have mentioned that. I sometimes assume too much. I have 
attached the file texmacs.mac, with the controls characters embedded. If that 
doesn't work you can use emacs or some other editor that allows you to enter 
control characters. In emacs you type C-q then C-b or C-e for the characters.

At least it's finding the .ps file. I did mention this is a quick hack, no? ;)
