I'm with you!

If you're not afraid of dirty, dirty, hacks then I wrote a function  
which takes a string, and replaces any LaTeX commands it finds with  
the corresponding gnuplot symbol. It's not much, but it saves time  
looking up symbols.  Gnuplot's enhanced modes already treat ^, _, and  
curly braces like LaTeX.

You can find the code on my homepage: jonshea.com/code.html

I think when I wrote this function I intended it to have a sprintf  
built in for formating, but when I ran it just now I got an error on  
all_va_args, which I assume has been deprecated or replaced.

This function was inspired by an analogous (but much more complete)  
parser Matt Craig wrote in IDL, for IDL.

Good luck,
