Fortran 90

Fortran 90 is the new ISO standard for Fortran. The new standard builds on a wealth of experience gained in using Fortran in these areas and provides many new features to aid the tasks of the scientific programmer. These include whole array operations, pointers, modules, strong typing and operator overloading which make it a truly modern language. Investment in existing Fortran software is supported because FORTRAN 77 is part of the Fortran 90 standard.
