The Microsoft Macro Assembler (MASM) is an x86 assembler that uses the Intel syntax for MS-DOS and Microsoft Windows. For a time, it competed with Borland Turbo Assembler. IBM re-branded early versions under the name IBM Macro Assembler. Later versions were bundled with Microsoft Visual Studio.

This is a set of floppy disk that accompanies the Microsoft Mouse Programmers Reference. They contain sample code and libraries that programmers can use in their applications. Sample programs demonstrate mouse programming in interpreted Basic, QuickBasic, C and QuickC, Macro Assembler, FORTRAN, and Pascal.

The Microsoft MS-DOS OEM Adaption Kit is a set of source code and binary object files used by OEMs to add custom hardware support. Such hardware support could range from simple hardware add-ons to completely non IBM-PC hardware compatible x86 machines. By the time of MS-DOS 3.3, the market had mostly settled on generic IBM PC hardware clones that would run "vanilla" MS-DOS distributions. MS-DOS 3.2 was the first DOS version to have a true retail "vanilla" release.

The Microsoft OS/2 SDK includes pre-release builds of OS/2, beta development tools, sample code, and loads of documentation. These were released prior to the OS/2 1.0 and 1.1 releases. Microsoft charged $3,000 in 1987 for the SDK. It was criticized as overpriced, buggy, and slow.

The Microsoft Pascal Compiler is Microsoft's implementation of the ISO Pascal language for DOS, Xenix, and OS/2. It was among Microsoft's early language products provided for DOS. It was superseded by Microsoft QuickPascal. The Microsoft Pascal Compiler was licensed to IBM, who sold it as the IBM Pascal Compiler.

Programmer's Library is a comprehensive collection of the most useful reference information available for programmers in MS-DOS and OS/2 environments. With Programmer's Library you can instantly get authoritative information about programming from books, manuals, and sample code in the following categories: Microsoft OS/2 References, Microsoft Windows References, MS-DOS References, Microsoft Network References, Microsoft Systems Journal, Hardware References, Microsoft C Language References, Microsoft Macro Assembler References, Microsoft BASIC Language References, Microsoft Pascal Language References, Microsoft FORTRAN Language References valuable programs, data, and sample code files 1991 for DOS](/product/bookshelf/91).

Microsoft Source Profiler is an application speed analysis tool for use with Microsoft language products. Version 1.x supports both DOS and OS/2.

First released in 1991, Microsoft Visual Basic was a programming environment where one could build an application by visually creating the user interface first, and then adding code. In contrast, even the smallest Visual Basic basic programs could take reams of program code to write in C or C++. Visual Basic was extremely popular for business application programming. The language itself was an interpreted BASIC dialect, however speed was maintained through the use of reusable compiled libraries (DLLs and VBX controls). These however, limited application development to Microsoft Windows.

Mix C, from Mix Software, is a small and simple C compiler. It was sold alongside a well-written book on the C programming language. Later versions were known as Power C

MKS Toolkit for DOS is a Unix interoperability package for MS/PC-DOS. It provides Unix tools and commands that run natively under MS-DOS.

Multiscope Debuggers for Windows is a debugging system for Windows 3.0 and 3.1 that features a GUI debugging interface, C++ debugging, a crash analyzer, execution control, advanced breakpoint capability, message spying, and remote debugging. There were also versions for DOS and OS/2.

The Network Support Encyclopedia Professional Volume (NSEPro), was Novell's high-priced technical knowledge base on a CD-ROM. Intended for Novell support professionals, it contained up-to-date product support documentation in a searchable hypertext system.

Originally released in 1985 by Ansa Software and later sold to Borland, Paradox is a high-speed relational database product that integrates with Borland's "Turbo" products. It was notable for its Query By Example feature, and its Paradox Application Language. It was popular in the late 80s and early 90s, and competed against database product such as dBase, Symantec Q&A, Foxpro, Clipper, Clarion, DataEase, R:Base, and DataFlex.

Pascal/MT+ is an ISO 7185 compatible Pascal compiler sold by Digital Research as part of their CP/M product line. There were versions for CP/M-80, CP/M-68k, CP/M-86, and MS-DOS.

PDC Prolog, by Prolog Development Center, is an enhanced implementation of the Prolog language (a language associated with artificial intelligence development). Some early versions were marketed and published by Borland under the name "Turbo Prolog".

PowerBASIC is a continuation of Borland TurboBasic maintained by its original author, Robert S. Zale. It was originally notable as a BASIC compiler, when most BASIC environments were interpreted.

Power C, from Mix Software, was a low cost DOS-based C compiler targeted at the educational market. Earlier versions were known as Mix C

Microsoft QBasic, not to be confused with QuickBasic, is a stripped down version of the Microsoft QuickBasic product that replaces GW-Basic in MS-DOS 5.0 and later. QBasic is an interpreter only, and can not compile standalone executables. QuickBasic sources can be compiled into binary EXE files with QuickBasic or Visual Basic for DOS.

Microsoft QuickBasic, not to be confused with the lesser QBasic, was a Basic interpreter and compiler product loosely based on GW-Basic. Version 2.0 for DOS and later included an Integrated Development Environment. Microsoft also produced QuickPascal and QuickC with similar integrated environments.

Microsoft QuickC is a C compiler with an Integrated Development Environment, designed to compete with Borland Turbo C. It was targeted at home/hobbyist users with a much lower price tag than Microsoft's corporate-oriented professional products. Microsoft also produced QuickPascal and QuickBasic with similar integrated environments.

Microsoft QuickPascal was a short-lived dialect of Pascal created specifically to compete with Borland Turbo Pascal. It incorporated many Borland-specific features at the expense of backwards compatiblity with the earlier Microsoft Pascal product.

Quickpro Plus is a programming utility that automatically creates simple custom database applications as standalone BASIC program source files. The Quickpro Plus user can then take the resulting BASIC program and customize it further. It features reporting functionality, database calculations, and the ability to target multiple BASIC variants. There were versions for CP/M, DOS, TRS-80, Atari, and OASIS.

Quicksilver, originally named WordTech dBIII Compiler, is a dBase III Plus application compiler that produces high-speed ready to run standalone executables. It boasts assembler level speeds often faster than competing compilers. Plus clone. Both of these add a number of features such as Windowing, user defined functions, EMS memory support, graphing, and networking capability.

Provides additional libraries for Logitech Modula-2.

RM/Cobol, from Ryan-McFarland Corp, is a powerful cross platform Cobol compiler that creates fast and efficient compiled code.
