In 1985 Microsoft licensed MacFortran, which consisted of a native ANSI FORTRAN 77 compiler and graphical debugger. The availability of MD68000-based machines made 32-bit Unix viable on small machines, and Absoft offered Fortran compilers for Unix machines by Data General, HP, Sun Microsystems, Tektronix, and others. When Alpha Micro released their MC68000 based microcomputer, Absoft expanded their offerings to Motorola and the Macintosh. Absoft FORTRAN 77 for Apple Macintosh and Windows MIL-STD-1753 was absorbed into the ISO/IEC 1539:1991 standard and later ISO/IEC standards are MIL-STD-1753 compliant, and MIL-STD-1753 was dropped as superfluous in 1995. ![]() 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 released by the DoD in 1978 to standardize some features of Industrial Real-Time Fortran as extensions of Fortran 77. 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. Additional OEM contracts for Fortran compilers for various Unix variants followed. 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. The name Absolute Software was used at first, but the shortened name Absoft was adopted as a more practical trademark.Ībsoft's first major sales success was a $500K contract with Alpha Microsystems for worldwide redistribution rights of a Fortran 77 compiler compatible with their AMOS operating system using a Motorola 68000 series processor. 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. Together they started an audio store, Absolute Sound, in 1975. The principals of Absoft, Peter Jacobson and Wood Lotz, met at the University of Michigan. History Origins: Absoft FORTRAN 77 for MC68000 Systems On September 30, 2022, Absoft will cease operations. Single thread and parallel multithread support is controlled by the user and includes five optimization levels, OpenMP, Speed Math levels 0 through 9, and other advanced capabilities. The 32-bit version produces only 32-bit executables.Īll are bundled with a graphical debugger and an integrated development environment.
