Jonathan, Yes that worked I changed my statement to: gfortran -I "c:\program files\aspentech\aspen plus 2006.5\engine\commons" -xf77-cpp-input usrkpg2.f And it now works for all the common files in that directory. The new issue is that there are common files that must be included located in a different directory. I tried: -I "dir1" -I "dir2" which did not work, and -I "dir1" "dir2" and that did not work either. I am guessing there is some simple syntax thing I have wrong here.
