It was originally developed by <a href="/wiki/Anders_Hejlsberg" title="Anders Hejlsberg">Anders Hejlsberg</a> at <a href="/wiki/Borland" title="Borland">Borland</a>, and was notable for its very fast compiling. Turbo Pascal, and the later but similar <a href="/wiki/Turbo_C" title="Turbo C">Turbo C</a>, made Borland a leader in PC-based development tools. </p><p>For versions 6 and 7 (the last two versions), both a lower-priced Turbo Pascal and more expensive <b>Borland Pascal</b> were produced; Borland Pascal was oriented more toward professional software development, with more <a href="/wiki/Library_(computing)" title="Library (computing)">libraries</a> and standard library <a href="/wiki/Source_code" title="Source code">source code</a>. The name Borland Pascal is also used more generically for Borland's dialect of the language Pascal, significantly different from Standard Pascal. </p><p>Borland 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, while Borland's French office released version 7.01 on its FTP. <sup id="cite_ref-tp10_3-0" class="reference"><a href="#cite_note-tp10-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-tp302_4-0" class="reference"><a href="#cite_note-tp302-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-tp55_5-0" class="reference"><a href="#cite_note-tp55-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="History">History</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Turbo_Pascal&action=edit&section=1" title="Edit section: History"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><a href="/wiki/Philippe_Kahn" title="Philippe Kahn">Philippe Kahn</a> first saw an opportunity for Borland, his newly formed software company, in the field of programming tools. Historically, the vast majority of programmers saw their workflow in terms of the edit/compile/link cycle, with separate tools dedicated to each task. Programmers wrote <a href="/wiki/Source_code" title="Source code">source code</a> using a <a href="/wiki/Text_editor" title="Text editor">text editor</a>; the source code was then compiled into <a href="/wiki/Object_code" title="Object code">object code</a> (often requiring multiple passes), and a <a href="/wiki/Linker_(computing)" title="Linker (computing)">linker</a> combined object code with runtime libraries to produce an executable program. </p><p>In the early IBM PC market (1981–1983) the major <a href="/wiki/Programming_tool" title="Programming tool">programming tool</a> vendors all made compilers that worked in a similar fashion. For example, the <a href="/wiki/Microsoft_Pascal" title="Microsoft Pascal">Microsoft Pascal</a> system consisted of two compiler passes and a final linking pass (which could take minutes on systems with only floppy disks for secondary storage, even though programs were very much smaller than they are today). This process was less resource-intensive than the later <a href="/wiki/Integrated_development_environment" title="Integrated development environment">integrated development environment</a> (IDE). Vendors of software development tools aimed their products at professional developers, and the price for these basic tools plus ancillary tools like <a href="/wiki/Profiling_(computer_programming)" title="Profiling (computer programming)">profilers</a> ran into the hundreds of dollars. </p><p>Kahn's idea was to package all these functions in an integrated programming toolkit designed to have much better performance and resource utilization than the usual professional development tools, and charge a low price for a package integrating a custom text editor, compiler, and all functionality needed to produce executable programs. The program was sold by direct mail order for <span style="white-space: nowrap"><a href="/wiki/United_States_dollar" title="United States dollar">US$</a>49.95</span>, without going through established sales channels (retailers or resellers).<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p><p>The Turbo Pascal compiler was based on the Blue Label Pascal compiler originally produced for the NasSys cassette-based operating system of the <a href="/wiki/Nascom" title="Nascom">Nascom</a> microcomputer in 1981 by <a href="/wiki/Anders_Hejlsberg" title="Anders Hejlsberg">Anders Hejlsberg</a>. Borland licensed Hejlsberg's "PolyPascal" compiler core (<i>Poly Data</i> was the name of Hejlsberg's company in Denmark), and added the user interface and editor.

A development system based on <a href="/wiki/BS_6192" class="mw-redirect" title="BS 6192">ISO standard Pascal</a> requires implementation-specific extensions for the development of real-world applications on the platforms they target. Standard Pascal is designed to be platform-independent, so prescribes no <a href="/wiki/Low-level" class="mw-redirect" title="Low-level">low-level</a> access to hardware- or operating system-dependent facilities. Standard Pascal also does not prescribe how a large program should be split into separate compiling units. From version 4, Turbo Pascal adopted the concept of <i><a href="/wiki/Unit_(Software_Development)" class="mw-redirect" title="Unit (Software Development)">units</a></i> from <a href="/wiki/UCSD_Pascal" title="UCSD Pascal">UCSD Pascal</a>. Units were used as external function libraries, like the object files used in other languages such as FORTRAN or C. </p><p>For example, the line <code>uses crt;</code> in a program included the unit called crt; the <code>uses</code> is the mechanism for using other compiling units. <code>interface</code> and <code>implementation</code> were the keywords used to specify, within the unit, what was (and what was not) visible outside the unit. This is similar to the <code>public</code> and <code>private</code> keywords in other languages such as <a href="/wiki/C%2B%2B" title="C++">C++</a> and <a href="/wiki/Java_(programming_language)" title="Java (programming language)">Java</a>. </p><p>Units in Borland's Pascal were similar to <a href="/wiki/Modula-2" title="Modula-2">Modula-2</a>'s separate compiling system. In 1987, when Turbo Pascal 4 was released, Modula-2 was making inroads as an educational language which could replace Pascal. Borland, in fact, had a Turbo Modula-2 compiler, but only released it on CP/M (its user interface was almost identical to that of Turbo Pascal 1–3) with little marketing. A much improved DOS version was developed, but as Borland was unwilling to publish the results, the authors including Niels Jensen bought the rights and formed <a href="/wiki/Clarion_(programming_language)" title="Clarion (programming language)">Jensen & Partners International</a> to publish it as JPI TopSpeed Modula-2. Instead Borland chose to implement separate compiling in their established Pascal product. </p><p>Separate compiling was not part of the standard Pascal language, but was already available in <a href="/wiki/UCSD_Pascal" title="UCSD Pascal">UCSD Pascal</a>, which was very popular on 8-bit machines. Turbo Pascal syntax for units appears to have been borrowed from UCSD Pascal.<sup id="cite_ref-26" class="reference"><a href="#cite_note-26"><span class="cite-bracket">[</span>26<span class="cite-bracket">]</span></a></sup> Earlier versions of Turbo Pascal, designed for computers with limited resources, supported a "chain and execute" system of dynamic linking for separately compiled objects, similar to the system widely used in BASIC. Also, the language had a statement to include separate source code in a program when necessary, and overlaying was supported from TP3, but, as with overlays, chained objects had to fit into the original (limited) program memory space. As computing and storage facilities advanced, the ability to generate large EXE files was added to Turbo Pascal, with the ability to statically link and collectively load separately compiled objects. </p><p>The .TPU files output by compiling a Turbo Pascal unit are tightly linked to the internal structures of the compiler, rather than standard .OBJ linkable files. This improved compiling and linking times, but meant that .TPU files could not be linked with the output of other languages or even used with different releases of Turbo Pascal unless recompiled from source. </p> <div class="mw-heading mw-heading3"><h3 id="Object-oriented_programming">Object-oriented programming</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Turbo_Pascal&action=edit&section=9" title="Edit section: Object-oriented programming"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>From version 5.5 some <a href="/wiki/Object-oriented_programming" title="Object-oriented programming">object-oriented programming</a> features were introduced: <a href="/wiki/Class_(computer_programming)" title="Class (computer programming)">classes</a>, <a href="/wiki/Inheritance_(object-oriented_programming)" title="Inheritance (object-oriented programming)">inheritance</a>, <a href="/wiki/Constructor_(object-oriented_programming)" title="Constructor (object-oriented programming)">constructors</a> and <a href="/wiki/Destructor_(computer_programming)" title="Destructor (computer programming)">destructors</a>.<sup id="cite_ref-tp55_5-1" class="reference"><a href="#cite_note-tp55-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> The IDE was already augmented with an object browser interface showing relations between objects and methods and allowing programmers to navigate the modules easily.

Program source code could be extended by using the include facility if the source code exceeded the memory limit of the editor. </p><p>There were different versions of Turbo Pascal for computers running DOS, CP/M, or CP/M-86 with 64 KB of memory and at least one floppy disk drive. The CP/M version could run on the many CP/M machines of the time with <a href="/wiki/Zilog_Z80" title="Zilog Z80">Z80</a> processors, or an Apple II with Z80 card.

The installer, lister, and compiler with its IDE, and the source code for a simple spreadsheet program called MicroCalc written by Philippe Kahn as a demonstration, would fit on a single floppy disc. A disc copy without MicroCalc would accommodate the source code and compiled executable of a reasonable-sized program—as it was common at the time for users to have only a single floppy drive as <a href="/wiki/Mass_storage" title="Mass storage">mass storage</a>, it was a great convenience to be able to fit both the compiler and the program being written on a single disc, avoiding endless disc swapping. </p><p>The <a href="/wiki/Computer_architecture" title="Computer architecture">architecture</a> of the various machines running MS-DOS additionally limited the maximum user memory to under 1 MB (e.g., <a href="/wiki/IBM_PC_compatible" class="mw-redirect" title="IBM PC compatible">machines hardware-compatible with the IBM PC</a> were limited to 640 KB). </p><p>The Turbo Pascal IDE was very advanced for its day.
