HI GCC and G77 gurus, I am interested in knowing how hard it will likely be to get a fortran program written for dos in lahey fortran 77 to compile and work under linux. I have inherited a nice environmental model, that is badly in need of updating, and restructuring. I don't know much about fortran, but want to incrementally convert it to c++. It's a leisure time project, with good potential to be useful. Anyway, any advice greatly welcomed. THanks, Matt
