That's not a particularly useful problem description if you don't show any hint at what those unsuccessful attempts looked like. Until then, see "help boxes". > My Perl language programs running in a Windows environment are > gradually being converted to Fortran F95 for increased calculation > speed. I have serious doubts that is going to work out. You would almost certainly be a good deal better off doing _your_ programming in Perl or Python, and just calling some F95 code from there. Or just do it all in an established number-crunching environment (R, MatLab, Octave, NumPy, you choose). Most of those have graphic capabilites of their own, too (some using gnuplot as a backend). > Does anyone know how that open pipe command would work for > Fortran F95 or gfortran? I guess not. But that's probably because you're asking the wrong people. That is entirely a Fortran issue. You open a pipe to (p)gnuplot exactly the same way as you would open a pipe to any other program. So it's a question of which standard library functions (FORTRANers apparently call those "intrinsics") come with your implementation of F95, and how portable your programs need to be between different platforms.
