Instructions for compiling simple F77 and F90 fortran programs. 1. WATFOR-77 compiler: Directory: kriz/for_test/f77/test3/ at the dos prompt > watfor77/noedit test3 This will create test3.lst, execute test3.exe and create test3.out without saving test3.exe . at the dos prompt > watfor77/noedit/exe test3 This will create a test3.lst file and a test.exe file at the next dos prompt > test3.exe generates test3.out 2. Lahey Fortran90 compiler: Directory: kriz/for_test/elf90/test3/ at the dos prompt > elf90 test3.f This will create test3.lst, test.map, test.exe files at the next dos prompt > test3.exe generates test3.out
