Absoft Fortran Compilers are set of Fortran compilers for Microsoft Windows, Apple Macintosh, and Linux produced by Absoft Corporation. The compilers are source code compatible across platforms.
All are bundled with a graphical debugger and an integrated development environment. Single thread and parallel multithread support is controlled by the user and includes five optimization levels, OpenMP and other advanced software engineering, and Speed Math levels 0 through 9.
The principals of Absoft, Peter Jacobson and Wood Lotz, met at the University of Michigan. Together they started an audio store, Absolute Sound, in 1975. In 1979, they noted the emergence of 16-bit microcomputers and saw a market for high quality Fortran compilers and built a compiler for the Western Digital WD16 microprocessor, which they released commercially in 1980. The name Absolute Software was used at first, but the shortened name Absoft was adopted as a more practical trademark.
Absoft’s first major sales success was a $500K contract with Alpha Microsystems for world-wide redistribution rights of a Fortran 77 compiler compatible with their AMOS operating system using a Motorola 68000 series processor. At this point Absoft still consisted of only the two founders, so this success allowed the company to remain independent, add staff, and move to a larger office facility. Additional OEM contracts for Fortran compilers for various Unix variants followed. The founders hired a manager for Absolute Sound which continued its success and expanded to three stores; the chain was sold to a larger Hi-Fi chain in 1988.
MIL-STD-1753 was released by the DoD in 1978 to standardize some features of Industrial Real-Time Fortran as extensions of Fortran 77. This extension added IMPLICIT NONE, DO WHILE, END DO to replace CONTINUE as the statement to end DO loops, and intrinsic functions for testing and setting bits. MIL-STD-1753 was absorbed into the ISO/IEC 1539:1991 standard and all Fortran and this and later ISO/IEC standards are MIL-STD-1753 compliant, and MIL-STD-1753 was dropped as superfluous in 1995.
