Gfortran should definitely be accepting a character in column 6 as an 
indication of line continuation in files with .f extensions unless 
you're using a compiler option that tells it to treat the file as 
free-form source.

(One possible problem is if you have tabs instead of spaces in your 
file, however.)

Could you please report the compiler options you are using, and the 
exact error message that you're getting with characters in column 6?

Thanks,
