Nevertheless, this feature is much less useful in FORTRAN than in laguages like PL/I, because the FORTRAN labels are restricted to numbers.
Unless you use a preprocessor, you cannot give descriptive names to the error handlers, so the equivalent FORTRAN code looks much uglier than in PL/I.
I should have said that alternate return is obsolescent in recent Fortran, and I don't remember ever feeling the need to use it, at least for error-handling.
