Borland Software Corporation was founded in 1983 by Niels Jensen, Ole Henriksen, Mogens Glad and Philippe Kahn. Its main business was the development and sale of software development and software deployment products. Borland was first headquartered in Scotts Valley, California, then in Cupertino, California and then in Austin, Texas. In 2009 the company became a full subsidiary of the British firm Micro Focus International plc.
Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal.
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. It was originally developed by Anders Hejlsberg at Borland, and was notable for its extremely fast compiling times. Turbo Pascal, and the later but similar Turbo C, made Borland a leader in PC-based development.
Turbo C is a discontinued integrated development environment (IDE) and compiler for the C programming language from Borland. First introduced in 1987, it was noted for its integrated development environment, small size, fast compile speed, comprehensive manuals and low price.
Anders Hejlsberg is a prominent Danish software engineer who co-designed several popular and commercially successful programming languages and development tools. He was the original author of Turbo Pascal and the chief architect of Delphi. He currently works for Microsoft as the lead architect of C# and core developer on TypeScript.
PowerBASIC, formerly Turbo Basic, is the brand of several commercial compilers by PowerBASIC Inc. that compile a dialect of the BASIC programming language. There are both MS-DOS and Windows versions, and two kinds of the latter: Console and Windows. The MS-DOS version has a syntax similar to that of QBasic and QuickBASIC. The Windows versions use a BASIC syntax expanded to include many Windows functions, and the statements can be combined with calls to the Windows API.
C++Builder is a rapid application development (RAD) environment, originally developed by Borland and as of 2009 owned by Embarcadero Technologies, for writing programs in the C++ programming language currently targeting Windows, iOS and for several releases, macOS and Android C++Builder combines the Visual Component Library and IDE written in Object Pascal with multiple C++ compilers. Most components developed in Delphi can be used in C++Builder with no or little modification, although the reverse is not true, but this constraint is valid only for source code. Binary code generated by Delphi can easily be linked to binary code generated by C++Builder and vice versa to generate an executable written in both Object Pascal and C++. With this approach, C++ can be called from Object Pascal and vice versa. Since both Delphi and C++ use the same back end linker, the debugger can single step from Delphi code into C++ transparently.
The Visual Component Library (VCL) is a visual component-based object-oriented framework for developing the user interface of Microsoft Windows applications. It is written in Object Pascal.
Delphi is a software product that uses the Delphi dialect of the Object Pascal programming language and provides an integrated development environment (IDE) for rapid application development of desktop, mobile, web, and console software, currently developed and maintained by Embarcadero Technologies.
Object Pascal is an extension to the programming language Pascal that provides object-oriented programming (OOP) features such as classes and methods.
Free Pascal Compiler (FPC) is a compiler for the closely related programming-language dialects Pascal and Object Pascal. It is free software released under the GNU General Public License, with exception clauses that allow static linking against its runtime libraries and packages for any purpose in combination with any other software license.
Turbo Assembler (TASM) is a computer assembler developed by Borland which runs on and produces code for 16- or 32-bit x86 DOS or Microsoft Windows. It can be used with Borland's high-level language compilers, such as Turbo Pascal, Turbo Basic, Turbo C and Turbo C++. The Turbo Assembler package is bundled with the Turbo Linker, and is interoperable with the Turbo Debugger. TASM can assemble Microsoft Macro Assembler (MASM) source using its MASM mode and has an ideal mode with a few enhancements. Object-Oriented programming has been supported since version 3.0. The last version of Turbo Assembler is 5.4, with files dated 1996 and patches up to 2010; it is still supplied with Delphi and C++Builder.
Virtual Pascal is a free 32-bit Pascal compiler, IDE, and debugger for OS/2 and Microsoft Windows, with some limited Linux support. Virtual Pascal was developed by Vitaly Miryanov and later maintained by Allan Mertner.
Turbo Vision is a DOS-based character-mode text user interface (TUI) framework developed around 1990 by Borland for Pascal and C++. Later it was deprecated in favor of Object Windows Library for the then-increasingly important Win16 API.
Turbo C++ is a discontinued C++ compiler and integrated development environment originally from Borland. It was designed as a home and hobbyist counterpart for Borland C++. As the developer focused more on professional programming tools, later Turbo C++ products were made as scaled down versions of its professional compilers.
Microsoft QuickC is a discontinued commercial integrated development environment (IDE) product engineered by Microsoft for the C programming language, superseded by Visual C++ Standard Edition. Its main competitor was Borland Turbo C.
Borland C++ is a C and C++ IDE for MS-DOS and Microsoft Windows. It was the successor to Turbo C++, and included a better debugger, the Turbo Debugger, which was written in protected mode DOS.
Turbo Delphi is a discontinued integrated development environment (IDE), created by CodeGear, which was targeted towards student, amateur, individual professionals, and hobbyist programmers. It used the Delphi programming language, which is a dialect of Object Pascal.
Turbo Debugger (TD) is a machine-level debugger for DOS executables, intended mainly for debugging Borland Turbo Pascal, and later Turbo C programs, sold by Borland. It is a full-screen debugger displaying both Turbo Pascal or Turbo C source and corresponding assembly-language instructions, with powerful capabilities for setting breakpoints, watching the execution of instructions, monitoring machine registers, etc. Turbo Debugger can be used for programs not generated by Borland compilers, but without showing source statements; it is by no means the only debugger available for non-Borland executables, and not a significant general-purpose debugger.
Delphi is a software product that uses the Object Pascal programming language and provides an integrated development environment (IDE) for rapid application development of desktop, mobile, web, and console software, currently developed and maintained by Embarcadero Technologies. Delphi evolved from Borland's "Turbo Pascal for Windows", itself an evolution with Windows support from Borland's Turbo Pascal and Borland Pascal with Objects, very fast 16-bit native-code MS-DOS compilers with their own sophisticated integrated development environment (IDE) and textual user interface toolkit for DOS. Early Turbo Pascal was written in a dialect of the Pascal programming language; in later versions support for objects was added, and it was named Object Pascal.
