IMHO. Has the comparison of a numeric value and a hollerith ever been allowed in a Fortran standard? If the answer is 'No', then you should (1) put the comparison behind an option, and (2) have gfortran issue an error without the option. If this is a DEC extension, then put it behind -fdec. If this misfeature is not a DEC extension but allow some ancient piece of code to compile, then put it behind -std=lagacy. -- steve
