GW-BASIC is a version of BASIC that was supplied with MS-DOS and as a replacement for IBM ROM basic. GW-BASIC replaced the earlier BASIC-86 supplied with some non-IBM OEM MS-DOS 1.x and 2.x. MS-DOS 5.0 and later replaced GW-BASIC with QBasic , a stripped down version of QuickBasic.

HyperPAD is a programming tool for DOS that mimics Apple's HyperCard. HyperPAD Programs are created visually, with menus and buttons on a set of pages, in an object-oriented environment. Applications are compiled and run within the HyperPAD operating environment. It is geared towards rapid application development of user interfaces, databases, and prototypes.

HyperScan is a Macintosh HyperCard program that scans images for use in other HyperCard stacks. You can also copy all or part of an image scanned with HyperScan, then past the copied image into a document in any program that supports pasting graphics. This requires the Ofoto software provided with the scanner.

The IBM 3270 Personal Computer High Level Language Application Program Interface (abbreviated "HLLAPI") is a software tool which enables users to develop microcomputer applications that transparently establish 3270 emulation sessions when host data is needed.

Beyond Basic BASIC, a Private Tutor course, teaches advanced techniques of IBM Personal Computer BASIC. This product includes BASIC subroutines you can use in your own programs. A member of the IBM Personally Developed Software and Education Family.

IBM's branded C compiler for the IBM PC/XT/AT computers. IBM C Compiler 1.00 is a rebadged version of Microsoft C 3.0

IBM C Set++ is a set of development tools that include an Presentation Manager based IDE, compiler, PM libraries, debugger, code browser, and on-line help. It later became "IBM VisualAge C++". OS/2 development may also require the IBM Developer's Toolkit.

IBM Cobol is a COBOL compiler for IBM's high end products.

Cobol is a high level language designed for use in business that uses English-like commands. IBM Cobol was one of the standard language products that IBM provided for the IBM Personal Computer running DOS and OS/2. Other standard language products included Fortran, Pascal, and Assembler. IBM Cobol compiler 1.0 is a licensed and rebranded OEM of Microsoft Cobol.

This is a floppy disk containing DOS based Common User Access sample programs. These sample programs are rough mockups that demonstrate the user interface standards specifications laid out by IBM. This was part of their Systems Application Architecture series.

IBM DB2, or Database 2, is a relational database originally developed for IBM's mainframe systems, and targeted at enterprise customers.

IBM's toolset and libraries for developing OS/2 applications. It may be used with IBM C Set++.

The IBM EZ-VU Editor 1.0 is an editor specifically designed for writing code for the IBM EZ-VU system. It appears to support some code formatting and highlighting features.

This is IBM's FORTRAN compiler software for the IBM PC. It was written by Microsoft and is similar to the Microsoft FORTRAN Compiler. up until IBM Fortran/2.

The IBM Graphics Development Toolkit is a set of program code and tools used to create device independent graphics drivers for use with the IBM PC and IBM's different video cards. Programs written to work with VDI drivers can work with different video cards just by installing a supplied driver.

This is IBM's release of the Logo graphical programming language for the IBM PC. It was considered a robust implementation with many features that took advantage of IBMs new PC hardware.

IBM Macro Assembler is an IBM OEM rebranded release of Microsoft Macro Assembler, and was intended only for use with the IBM PC. Macro Assembler provides support for writing programs directly in the 8088/8086's native machine language.

The IBM PASCAL Compiler is a tool that compiles Pascal source code in to binaries for IBM PC-DOS. Pascal is an easy to use structured high level language with simplified English commands. It was geared towards educational markets, yet powerful enough ti create sophisticated programs. The IBM PASCAL Compiler is an IBM OEM version of the Microsoft Pascal Compiler. This was one of the standard language products that IBM provided for the IBM Personal Computer. Other standard language products included Fortran, Cobol and Assembler.

The Personal Computer BASIC Compiler is a BASIC language compiler written by Microsoft and licensed to IBM for use on the IBM Personal Computer. It is mostly compatible with BASIC code written for IBM Cassette/Disk basic, however the compiled code will run much faster and eliminates the need to distribute source. Compiled programs do not require IBM BASIC in ROM.

The IBM Personal Computer Graphical File System is a programming library add-on to the IBM Personal Computer Graphical Kernel System. It provides a programming interface for drawing and rendering device independent metafiles. Both the GFS and the Professional Graphics Series were designed primarily to support the high end CAD oriented IBM Professional Graphics Controller.

IBM Personal Computer Graphical Kernel System is a standardized graphics interface programming library designed to simplify portable software development across IBM's different video card. It provides bindings for languages, including BASIC, C, and FORTRAN. It was primarily designed for use with the IBM Professional Graphics Adapter. The IBM PGA card is a very high end, and very uncommon, video card designed primarily for use with CAD programs.

IBM Personal Computer Plotting System is a set of business graphing program libraries for use with the IBM Personal Computer Graphical Kernel System. It also includes a graphing demonstration program. GKS is a shared, standardized graphics library, designed primarily to support IBM's high end CAD oriented IBM Professional Graphics Controller. GKS supports IBM's other video systems through the use of interchangeable device drivers.

The IBM Professional Debug Facility is a terminate-and-stay-resident debugging tool. You can use it with programs that can not be debugged with DOS DEBUG. It avoids DOS I/O calls to prevent conflicts with the running program.
