CodeView was a standalone debugger created by David Norris at Microsoft in 1985 as part of its development toolset. It originally shipped with Microsoft C 4.0 and later. It also shipped with Visual Basic for MS-DOS, Microsoft Basic PDS, and a number of other Microsoft language products. It was one of the first debuggers on the MS-DOS platform that was full-screen oriented.

Crystal Reports, from Crystal Services/Seagate Technology Inc., is a powerful visual report creation tool for Microsoft Windows. Rather than a specific product, it is designed to work with almost any existing database product. reports from directly from within their applications. Crystal Reports was sometimes bundled with Microsoft Visual Basic. And it can be used with Crystal Reports Server for scheduled report generation.

dBFast is a dBase application compiler for DOS, the Microsoft Windows environment, and Macintosh. The DOS version was considered very limited and buggy. The Windows version was first released in 1989 for Windows 2.x, and supposedly the first "relational" database for Windows. changes. Windows specific features include support for mouse, buttons, menus, Dynamic Data Exchange, graphing, and graphics data fields.

dGraph is a dedicated graphing package specifically designed to create graphs and charts from data stored in dBase databases. Fox and Geller also produced an almost identical product named RGraph, designed specifically for creating charts using R:Base databases.

Digital Research C is a compiler developed for use with Digital Research's CP/M systems. It was also ported to DOS.

PL/I is a programming language oriented towards scientific and business programming. Digital Research provided implementations for their CP/M operating system as well as MS-DOS.

Smalltalk/V was the first widely available version of Smalltalk. It was developed by Digitalk in 1986 for DOS, Macintosh, and later Windows.

The Display Enhancement Packageby OAK Tree Systems This is a library that permits easy access to the the TI-99/4a 40-colum video text mode.

DIV Games Studio, from Hammer Technologies, is an all-in-one software program for DOS for creating your own (DOS) games, using a programming language similar to C or Pascal. The software includes an integrated development environment with code editor, graphics editor and sound editor.

Draw 'n Plot, from Quality 99 Software, is a drawing application and library for the TI-99/4A with Extended Basic, that adds the ability to use bit-mapped graphics.

Access Manager is a database programming library sold by Digital Research. It supports key fields, b-tree indexes, record locking, and deleted records. It is designed for use with Digital Research language products including DR C, CBASIC, PL/I, and Pascal MT+, and may be used alongside the Display Manager programming libraries. There were versions for both CP/M and MS-DOS.

Display Manager is a programming library from Digital Research that abstracts the physical display or terminal type from the application. It is designed for use with Digital Research language products including DR C, CBASIC, PL/I, and Pascal MT+, and may be used alongside the Access Manager programming libraries. There were versions for both CP/M and MS-DOS.

DRI Programmer's Utilities, from Digital Research, includes Lib86, Link86, Rasm86, and Xref86, for use with DRI programming languages.

Editor Assembler is a native development system for the TI-99/4A. It features a text editor, a TMS9900 machine code assembler, and sample code including an assembler version of "Tombstone City".

Exploring Pascal, published by Aston-Tate, is a disk of sample tutorial programs included with a SofDesign tutorial book for Pascal.

Forehelp is a Windows Help Authoring Tool for Microsoft Windows 3.x.

Microsoft FORTRAN Powerstation was a rebranding of Microsoft's earlier Microsoft Fortran product. It featured support for 32-bit DOS and Microsoft Windows.

Foxgraph, released in 1988, is a 2D and 3D business graphing module add-on for Foxbase Plus. It contains a number of predefined graph types but is highly flexible and customizable. FoxGraph was based on "Perspective", a graphing program from Three D Graphics. Perspective is also what Boeing Graph was based on. There were versions for PC and Mac. FoxBase and related products were acquired by Microsoft.

FoxPro, originally from Fox Software and later Microsoft, is a relational database that clones the functionality of dBase IV, but offers vast speed improvements. It was based on Fox Software's FoxBASE (a dBASE II clone) and FoxBASE+ (a dBase III Plus clone). It adds a new mac-like user interface that was first developed for FoxBASE+/Mac.

FontRunner, from Apex Software, is a dBase application compiler that specialized in making small, fast, terminate-and-stay-resident database applications. This makes it possible for DOS application users to call up data entry screens without the need to exit the program they are running. It supports redefinable keyboard macros, and can copy data from a DOS application screen into its database. To reduce memory usage it omits dBase's reporting and label generating capabilities. Version 1.2 and later support EMS memory usage.

This is a set of libraries and tools used to develop GEM 3 applications. The GEM Programmer toolkits were marketed with portability, both in terms of the 'C' compilers supported, as well as the M68k platform.

These are the tools needed to develop GEOWORKS application software.
