NAGWare f95 Compiler
The NAGWare f95 Compiler, derived from the world's first Fortran 90 Compiler from NAG is robust, highly tested, and valued by developers all over the globe for its checking capabilities and detailed error reporting. Available on a wide range of Unix and Windows platforms it accepts fixed or free format Fortran 95 input and many common Fortran 77 extensions are allowed. A large number of Fortran 2003 language features are now available. HPF code is also compiled and checked though only single processor output is generated.
Enhancements at Release 5.1
NAG is pleased to announce that a major new release of the NAGWare f95 Compiler - Release 5.1 - is now available. Release 5.1 continues the long line of ever-improving NAGWare Compilers that started with the world's first Fortran 90 compiler - NAGWare f90, which was released in 1991.
Release 5.1 continues to support the full Fortran 95 language, while retaining backwards compatibility to previous releases. Additional new Fortran 2003 enhancements provide early access to more of the Fortran language of the future. These include the addition of more object-oriented features to add to those that established Release 5.0 as a leader in this area. The C Interoperability enhancements bring a standard means of calling C code from Fortran and vice versa. This new release also makes available further Fortran 2003 advances, for example in the areas of Input/Output and access to the computing environment.
Key features of the new release are improvements in performance and error checking. NAGWare f95 is available now on all major Unix platforms.
