You should probably have converted from pgnuplot.exe to the actual 
console version, gnuplot.exe years ago...

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".

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).

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.
