Kahn's idea was to integrate these separate functions in a programming toolkit, have it run with much better performance, and charge one low price for it all. Vendors of software development tools aimed their products at professional developers, and the price for these basic tools plus ancillary tools like profilers ran into the hundreds of dollars. This process was the cumbersome product of the extremely limited resources of the early IBM PC models. For example, the Microsoft Pascal system consisted of two compiler passes and a final linking pass (which could take minutes on systems with only floppy disks for secondary storage). They all made C compilers (and some made Pascal compilers), which all worked in a similar fashion. In the IBM PC market of the early 1980s, the major programming tool vendors included IBM, Microsoft, and Lattice. Programmers wrote source code and entered it using a text editor, a compiler created object code from source (often requiring multiple passes), and a linker combined object code with runtime libraries to produce an executable program. Historically, the vast majority of programmers saw their work flow in terms of the edit/compile/link cycle, with separate tools dedicated to each task. Philippe Kahn first saw an opportunity for Borland, his newly formed software company, in the field of programming tools. The name Borland Pascal is also used more generically for Borland's dialect of Pascal.īorland has released three versions of Turbo Pascal of historical interest free of charge: versions 1.0, 3.02 and 5.5 for MS-DOS. The name Borland Pascal was generally reserved for the high end packages (with more libraries and standard library source code) while the original cheap and widely known version was sold as Turbo Pascal. Turbo Pascal is a complete software development system that includes a compiler and an Integrated Development Environment (IDE) for the Pascal programming language running under CP/M, CP/M-86, and MS-DOS, developed by Borland under Philippe Kahn's leadership.
