Re: Fortran and tclForces

Hi Luca,
namd is using an embedded tcl interpreter, so what this really comes
down to is finding a way to call a fortran routine from tcl. I have done
this many times with C or C++ code called from tclforces by using swig
( to create the interface, which is fairly easy and
works quite well. I've never done the same thing with fortran, but I do
know that it is possible. You may want to check out Axel Kohlmeyer's
posts to VMD-L over the last two days, as he has been covering a similar
issue over there in a more fortran-centric way. You might also google
around a bit for fortran/tcl interfaces, since that's really what you're
