Absoft Pro Fortran Suite for Mac OS X PPC

Absoft Pro Fortran for Mac OS / Intel systems (Rosetta)
Absoft Pro Fortran for Mac OS / G5 systems

Absoft Pro Fortran is the only commercially available Fortran compiler solution compatible with both Mac OS / G5 and Mac OS /Intel

Product OverviewAbsoft Pro Fortran for Mac OS is compatible with both Mac OS / G5 and Mac OS / Intel based systems – and it is the most complete solution in either environment. It runs native on Mac OS / G5 systems, installs in both 32-bit and 64-bit environments and can generate both 32-bit and 64-bit applications. With a few easy steps, it also installs and runs on the new Mac OS / Intel systems using Apple’s Rosetta. Code for G5 and Intel can be developed on a single system and building code between G5 and Intel Mac systems requires little more than a recompile. In addition to tremendous flexibility Pro Fortran provides the industry’s most complete Fortran development solution. Each copy includes: Fortran 95 (64/32-bit) and C/C++ compilers (32-bit G5 only), a powerful Integrated Development Environment (IDE) designed for Fortran programmers, programmer’s editor, the industry-leading Fx2 debugging solution, MRWE application framework, math and VAX/Unix compatibility libraries, graphics libraries, and free technical support.For Mac OS / G5 companion products such as VNI’s newest IMSL 5.0 Fortran numerical libraries are available in 64-bit and 32-bit versions. To take maximum advantage of the G5’s vector processing capabilities, the VAST auto-vectorizing and auto-parallelizing source code pre-processors are available as options. Power users on Mac OS Intel may want to purchase Pro Fortran for Mac OS Intel.

Product Description

Fully compatible with OS X 10.4 and OS X 10.3.9 and tuned for G5, or Rosetta on Intel, Pro Fortran includes an ANSI/ISO Fortran 95 compiler capable of generating both 64-bit and 32-bit executables and C/C++ (32-bit G5 only) compiler, all of which are link and debug compatible with Apple C and other tools. Pro Fortran includes a powerful IDE which supports additional compilers and select third party applications such as IMSL and VAST auto parallel and vectorizing tools as plug ins on G5. Stand alone applications can be created with the click of a mouse. Also included are 2D/3Dgraphics, BLAS, ATLAS, LAPACK90 and HDF libraries and free technical support from friendly engineers included at no additional charge. Free standing applications can be created automatically.

The programmer’s editor uses color syntax to highlight key words and data types. The AbsoFx2™ Debugging Solution fully supports Fortran and intermixed C and assembly code. Create mixed language applications with Fortran, C/C++ and assembler using the single Absoft environment. For users working in multiple environments, multi-platform discount bundles are available.
Absoft’s no-charge companion home license policy allows registered customers to install Pro Fortran on their home system for personal use at no additional cost. Each license includes Absoft premier technical support, free service packs and periodic software fixes at no additional charge.

Complete IDE (Integrated Development Environment) includes programmer’s editor, compilers, multi-language debugger with Carbon interface, application framework and support for XL Fortran and XL C/C++. Full link and debug compatibility with Apple C. All compilers can be run from GUI or command line. IDE is easy to use but very powerful and flexible for advanced users.

Back to Special Features


The Absoft Editor is a powerful and flexible tool for creating and maintaining program source files in FORTRAN 77, FORTRAN 90/95, C and C++. The editor is source language sensitive and will display keywords and comments in different text colors, making keywords easier to distinguish in your source code. With the Absoft Editor, you can edit multiple files at the same time, launch a compiler, and return to the editor to correct syntax errors detected by the compiler. The Absoft Editor is a Mac OS X program. Third party editors are also supported.

Application Framework

MRWE (Macintosh Runtime Window Environment) can automatically add a basic Mac style interface to any compiled application. Written entirely in Fortran 95, full, documented source is provided as example of writing Carbon applications which access the Mac toolbox. MRWE can easily be modified to add special features or change functionality.

Back to Special Features


Pro Fortran for Mac OS X includes a version of PLplot, a library of functions that are useful for making scientific plots. PLplot can be called from C, C++ and FORTRAN. The PLplot library can be used to 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. There are almost 2000 characters in the extended character set. This includes four different fonts, the Greek alphabet and a host of mathematical, musical and other symbols. PLplot requires OS X 10.1 or later. PLplot is available for OS X, Windows, x86/Linux and x64/Linux making porting graphics between any of these environmets a straightforward process. Complete documentation is provided in pdf format. PLplot is provided under LGPL.

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.
