I had asked about public domain FORTRAN for YDL, and someone told me that g77 is part of the installation. I have done a search for g77 and did not find it. I did a search for f77 and found it located in /usr/share/apps/kdevfilecreate/file-templates/f77. I tried to run what I believed to be f77 and got a permission denied message. Where is g77 located?
