Hi Joe,

What do you mean by chemistry code? If you mean graphics code then most
of the code is written in c or c++ (I belive) but if you refer to the so called
number crunching then most of the code is still done in fortran (I believe).

As far as I know there are work going on for rewriting old MD/MM code into c.
I would be happy to see how close good c-coding comes to old fortran coding
in the sence of computation efficiency. The tests I made on our Cray showed
that good vector fortran coding is still much faster than my c-code. Does
anybody know if this is still the case? On normal workstations the c-code
should be pretty close to fortran code.

I don't know what people think but as an old fortran programmer I now do
everything in c and I really would never change back to fortran.

Cheerio,
