GNUFOR: a Gnuplot / Fortran interface

GNUFOR is a simple Fortran 90 interface by John Burkhardt to the Gnuplot plotting software. GNUFOR makes it possible, while running a Fortran program, to generate some data and request an immediate plot. This is done by issuing a system command that starts up Gnuplot, and feeding it the appropriate commands and data. The Fortran program pauses while the graph is displayed, and the user can admire the plots for a while, before hitting return and giving control back to the FORTRAN program.
