The integrated Pascal compiler was of good quality compared to other Pascal products of the time. On its launch in the United States market, Turbo Pascal retailed for US$49.99, a very low price for a compiler at the time. The compiler was first released as Compas Pascal for CP/M, and then released on 20 November 1983 as Turbo Pascal for CP/M (including the Apple II computer when fitted with a Z-80 SoftCard, effectively converting the 6502-based Apple into a CP/M machine, the Commodore 64 with CP/M cartridge, and the later DEC Rainbow), CP/M-86, and DOS machines. Anders Hejlsberg joined the company as an employee and was the architect for all versions of the Turbo Pascal compiler and the first three versions of Borland Delphi. Borland licensed Hejlsberg's "PolyPascal" compiler core ( Poly Data was the name of Hejlsberg's company in Denmark), and added the user interface and editor. The Turbo Pascal compiler was based on the Blue Label Pascal compiler originally produced for the NasSys cassette-based operating system of the Nascom microcomputer in 1981 by Anders Hejlsberg. The program was sold by direct mail order for US$49.95, without going through established sales channels (retailers or resellers). Kahn's idea was to package all these functions in an integrated programming toolkit designed to have much better performance and resource utilisation than the usual professional development tools, and charge a low price for a package integrating a custom text editor, compiler, and all functionality need to produce executable programs. 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 less resource-intensive than the later integrated development environment (IDE). 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, although programs were very much smaller than they are today). In the early IBM PC market (1981–1983) the major programming tool vendors all made compilers that worked in a similar fashion. Programmers wrote source code using a text editor the source code was then compiled into object code (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 workflow 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 the Pascal programming language, significantly different from Standard Pascal.īorland has released three old versions of Turbo Pascal free of charge because of their historical interest: the original Turbo Pascal (now known as 1.0), and versions 3.02 and 5.5 for DOS. Turbo Pascal, and the later but similar Turbo C, made Borland a leader in PC-based development.įor versions 6 and 7 (last), both a lower-priced Turbo Pascal and more expensive Borland Pascal were produced Borland Pascal was more oriented toward professional software development, with more libraries and standard library source code. It was originally developed by Anders Hejlsberg at Borland, and was notable for its extremely fast compilation. Turbo Pascal is a software development system that includes a compiler and an integrated development environment (IDE) for the Pascal programming language running on CP/M, CP/M-86, and DOS.
