I downloaded your euphoria to java converter when you first announced it, but I
was (and still am) running Linux and JAVA.EX uses dos shell commands which are
incompatible in Linux..  Sorry I didn't mention yoir project in my e-maill - I
had forgotten you were already working on such a program. If you want to make
your program compatible with Linux, use rm -f instedad of del and use mv
instead of rename.

The program I had written before was part of my bytecode Euphoria project. I
never got very far with it, and I don't think I have it anymore - the rest of
my bytecode euphoria files are on my website at
http://JJProg.tripod.com/compiledeu.html, including an interpreter in C++ and
an interpreter in Euphoria. Currently, the compiler doesn't parse standard
Euphoria, but a high-level assembly language with Euphoria sequences and
functions. I haven't done much work on it lately, though.
