Absoft Pro Fortran is the most complete Fortran compiler solution for Windows users available. Aggressively optimizing the F95 Fortran compiler provides superior performance for compiled applications. Special optimizations maximize application performance on 32-bit and 64-bit AMD and Intel processors. Pro Fortran is fully link and debug compatible with Microsoft C and .NET but does not require Visual Studio and is not affected by Microsoft's licensing policies or additional cost. The Pro Fortran Integrated Development Environment is powerful and designed to accommodate the needs of both seasoned professionals and beginning developers.  The IDE supports select third-party products as plug-ins. Pro Fortran includes everything developers need in a single integrated package.

The Absoft Pro Fortran Compiler Suite for Windows:

The process of combining Fortran and C routines into a single application has been a major frustration to many Windows programmers. Microsoft requires use of non-standard Fortran syntax to accomplish this feat. Absoft Pro Fortrans provide a better solution: Absoft Fortran compilers are link-compatible and use standard Microsoft C calling conventions. Mixed Fortran/C applications are easily generated entirely from within the Pro Fortran development environment or can be easily linked with code created in Microsoft C. Example code is provided in the documentation. Pro Fortran compilers are also debug-compatible with the Microsoft C compiler included with the Microsoft platform SDK..

DLL building capabilities

Pro Fortran can automatically build Fortran-based DLLs compatible with Microsoft Visual C++, Microsoft Visual BASIC, Microsoft Excel, Delphi, and Borland C++. Example code is contained in the documentation. Absoft's alias feature allows you to create DLLs compatible with any other configuration.

• Help guide for Visual Basic .NET located here.
• Information on calling unmanaged DLL's from Visual C++ .NET located here.
   

Graphics Libraries

Pro Fortran includes a new, flexible graphics library called PLplot. PLplot can be called from Fortran as well as C, and C++ and can create standard x-y plots, semilog plots, log-log plots, contour plots, 3D plots, mesh plots, bar charts and pie charts. Multiple graphs (of the same or different sizes) may be placed on a single page with multiple lines in each graph.
Output can be to your monitor, a file, a printer or in postscript format. There are almost 2000 characters in the extended character set including four different fonts, the Greek alphabet and a host of mathematical, musical and other symbols.

PLplot is included on all versions of Pro Fortran and is source compatible across Linux, Windows and Mac platforms (additional details available at: http://plplot.sourceforge.net/).

HDF precompiled libraries are included with every copy of Pro Fortran.

Live, industry-leading technical support - Absoft has the reputation of the best Fortran technical support in the industry and is the best choice for a single point of contact for customers to receive top quality support.

Lowest price - Not only do our new, lower prices give you the best price/performance available, Absoft offers the only Fortran compilers with MaxFlex licensing which allows licenses to be reused freely across different platforms (Linux, Windows, OS X) from a single license server. These features represent significant cost savings for developers working in environments where computers and compilers need to be shared across multiple systems.

Absoft's Fortran Compiler for Linux is unrivaled in both ease of use and its comprehensive list of features and typically generates code that performs as fast or faster than any other Fortran compiler. Absoft 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 data types as well as others from IBM/VS, Cray, Sun FORTRAN and FORTRAN 66 conventions. PIC code, automatic byte swapping, full integration with GNU tools and LSB compliance means porting code from any environment with Absoft requires little more than a recompilation. The easy-to-use Absoft Fortran compiler "just installs". A 2D/3D pre-compiled graphics library, pre-built BLAS, ATLAS and LAPACK90 libraries and technical support from friendly engineers is included at no additional charge.

Absoft is the only Fortran vendor offering bundle pricing on source-compatible Fortran solutions for all of today's popular computing platforms (Windows, Macintosh, and Linux). Customers save time and money with source-compatible Fortran solutions for all their development environments.
