hi, having supported Pafec and then in a different job flow3d, i was most interested in anything that could make large fortran packages more manageable. there was a commercial package called Spag i which claimed to un-spagatti-ify your code which i always wanted but, could never afford. the best i managed was sed and awk scripts to split huge fortran files into one file per function and build a makefile. this at least made rebuilds quicker. i do not miss maintaining fortran code hacked by dozens of people over many decades. -Steve
