Microsoft Fortran 4.1 - Optimizing Compiler

The Microsoft FORTRAN Optimizing Compiler for the MS-DOS operation system implemented the full ANSI standard for the FORTRAN programming language.  The FORTRAN language is a powerful, general-purpose programming language especially suited to complex scientific, mathematical, engineering, and financial algorithms.  The Microsoft FORTRAN Optimizing Compiler provides all of the features required by the ANSI standard, plus many powerful extensions to the standard FORTRAN language.

The Microsoft FORTRAN Optimizing Compiler generates fast, efficient native code.  The library that you build using the SETUP program provided with the compiler includes code for fast real arithmetic if an 8087/80287 coprocessor is used (you can get a coprocessor if you Visit My eBay Store).  It can also provide for software emulation of 8087/80287 operations for those systems without a coprocessor.  An alternate math package is available to maximize program speed on systems that do not have a coprocessor installed.

It also includes the following features:

Full ANSI 77 FORTRAN 
GSA certified error free at Full level
A full set of intrinsic functions, including standard IBM VS and DEC VAX functions
The Microsoft CodeView debugger, a window-oriented, source-level debugger that makes it easy to find and correct errors in source programs
A choice of multiple and mixed memory models (medium, large and huge) to set up the combination of data and code storage that best suits your FORTRAN programs
Math support, including floating point emulation, 8087/80287 coprocessor support and alternate math support for systems without coprocessors
Large program support
Extensive diagnostic error messages
Interlanguage calling support, which allows you to link Microsoft FORTRAN programs with 8086 assembly-language programs and Microsoft C and Pascal programs
DOS 3.0 networking support, including record and file locking and file sharing
Compatibility with the XENIX operating system at the source code level
A complete development environment, including the CodeView symbolic debugger, the Microsoft Overlay Linker (LINK), the Microsoft Program Maintenance Utility (MAKE), and the Microsoft Library Manager (LIB)
