Faster code, PLUS a better development environment! Absoft simplifies code development by solving the problems associated with IDEs such as Visual Studio and Xcode - excellent for C++, but with no knowledge of Fortran. The Absoft IDE supports both Fortran and C and automatically provides proper syntax sensitivity, array indexing, etc. for each language. It includes everything you need: F95 compilers, programmer's editor, Fx3 graphical debugger, application framework, graphics and optimized math libraries in a single, easy-to-use package.

Single Solution - Linux, Windows and MacOS. Simplify code development for multiple platforms. Absoft provides same look and feel on every platform and allows you to build native applications for Linux, Windows and Mac from a single code base! Absoft's exclusive MaxFlex license manager allows a single license to float across Linux/Windows/Mac, saving you time and money.

Compatibility and Companion Products

Absoft Pro Fortran uses an extended version of the Cray CF90 front end and adheres to the latest ISO and ANSI Fortran 95 standards. Extensions from all major workstations have been added to make sure your code ports from any environment with minimal effort. Absoft Fortran compilers conform to all DoD MIL-STD 1753, FIPS 69-1, and POSIX standards, support most popular VAX/VMS extensions including RECORD, STRUCTURE, POINTER, and UNION, (per V5.4 of VMS FORTRAN), QUAD (REAL*16) data types as well as others from IBM/VS, Cray, Sun FORTRAN as well as FORTRAN 66 conventions. Automatic byte-swapping and full integration with many third party tools means porting code from virtually any environment requires little more than a recompilation without rewriting code. The F95 compiler can operate in F95, F90 or F77 modes.
