Except for a few differences, which will probably not affect you, see the documentation of the -ff2c command-line option of gfortran. Additionally, procedures which require an explicit interface (and which therefore couldn't be written in Fortran 77) pass array descriptors. Those are not documented outside gfortran's source code. - Tobi
