NAS Fortran 90+

A full 32 bit Fortran 90 compiler and development system for OS/2, DOS and MS Windows that included a debugger, message parsing mapper, numerical libraries and translators of older FORTAN code. Although sold and supported by the UK based N. A. Software company, it was actually a version of the OCCL Algol 68 compiler by Oxford and Cambridge Compilers Ltd. Like its sister Algol 68 product it supported offloading numerically intensive tasks to transputer cards or farms, or MEIKO massively parallel supercomputers. There was later a variant called "High Performance Fortran-Plus" that was developed in association with some EU based research organisations that offered a higher performance of numerically intensive code, better parallelisation support and better support of multi-computer workloads.

The compiler was sold until 2003 when NASoftware stopped supporting all platforms except native MS Windows. There is no support available for the product any more as the company had to stop selling their Fortran compilers altogether later in the decade when code developer OCCL went out of business.
