Since the first versions didn't have online help, copy protection was effectively enforced by possession of the Turbo Pascal reference manual (pictured above).

Turbo Pascal came with the famous "Book License": "You must treat this software just like a book. Turbo Pascal is generally considered to be the first popular Integrated Development Environment (IDE) of any type.Īs an additional selling point against the bigger vendors, Turbo Pascal disks came with no copy protection of any sort. Instead of selling the kit through established sales channels (retailers or resellers), his new tool would be sold inexpensively via mail-order. You will be able to see the internal functions, data structures, algorithms, tips and tricks used by the compiler. 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. Of course, this is not the original source code of the compiler since it was not written in Pascal, but the code of a compatible compiler written in Turbo Pascal. Programmers wrote source code and entered it using a text editor, a compiler then created object code from source (often requiring multiple passes).

Because some people dont have TP 6.0, I have also made a version of the source code for TP 5.5, which is available for free at Borlands Museum (requires free registration). 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. The game was originally written in Borland Turbo Pascal 6.0, which supports inline assembly. This process was the cumbersome product of the extremely limited resources of the early IBM PC models. Earlier versions of Turbo Pascal, designed for computers with limited resources, had no real need for it (the language had a statement to include separate source code in a program when necessary, and overlaying was supported from TP3) but, as computing and storage facilities advanced and the ability to generate large EXE files was added to Turbo Pascal, programs became large and complex enough. 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. Very simple little program designed for the purpose of getting the computer to solve a blocks game. PCX2TPI is a programmer's tool to convert 16-color PCX images to a format that can be linked into EXEs created using Turbo Pascal.
In the IBM PC market of the early 1980s, the major programmer tool vendors included IBM, Microsoft, and Lattice. Pascal source code for viewing PCX files. This cycle was the result of limited computer power and small amounts of memory.
Programmers wrote code in 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.
