Using g77: 1. Run command.com to get a DOS prompt. 2. Switch to the g77 directory (probably c:\g77). 3. Type g77setup. 4. If you get an "Out of Environment Space" error, close programs and try again with more memory free. 5. Now switch to the mietable source directory. 6. Type g77 mietable.f -o mietable.exe 7. This should generate no errors or warnings. Note that mietable.f makes use of the INCLUDE keyword, so it is not strictly ANSI F77.
