Turbo Pascal came with the "Book License": "You must treat this software just like a book. Unlike some other development tools, Turbo Pascal disks had no copy protection. The program was sold by direct mail order for $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.

6.5 Issue with CRT unit on fast processors.

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 compiling times. 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. Remember, a working compiler is the best book on compiler construction.CP/M, CP/M-86, DOS, Windows 3.x, Macintosh If you take a look at prices of compiler construction books you will soon figure out that the price I am asking for a working compiler is lower than the price of top books on compiler desing and construction. If you are interested in the compiler you can purchase the complete source code of the TPC16 (DOS application, compiles with Turbo Pascal) and TPC32 (WIN32 application, compiles with Delphi 7). However, if you would like to use the compiler for your own project then you can get the source code in exchange for small compensation for the effort I put into the compiler. You can use published algorithms and data structures without any limitations. If you are interested in Turbo Pascal compiler internals then you will get all the answers here. While most important functions of the compiler are described here in details, I decided not to offer the compete source code of the compiler for free.
