Turbo Pascal while working at Initial release 1983; 34 years ago ( 1983),,,, /,, Turbo Pascal is a software development system that includes a and an (IDE) for the running on,, and, developed by under 's leadership. For versions 6 and 7 (last), both a lower-priced Turbo Pascal and more expensive Borland Pascal were produced; Borland Pascal was more oriented towards professional software development, with more libraries and standard library source code. The name Borland Pascal is also used more generically for Borland's dialect of the Pascal programming language, significantly different from Standard Pascal. 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. Contents • • • • • • • • • • • • • • • • • • • Motivation and release [ ] 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.
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 MS-DOS, developed by Borland under Philippe Kahn's leadership. For versions 6 and 7 (last), both a lower-priced Turbo Pascal.
Programmers wrote using a; the source code was then compiled into (often requiring multiple passes), and a combined object code with runtime libraries to produce an executable program. In the early IBM PC market (1981–83) the major vendors all made compilers that worked in a similar fashion. For example, the 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). This process was less resource-intensive than the later (IDE).
Vendors of software development tools aimed their products at professional developers, and the price for these basic tools plus ancillary tools like ran into the hundreds of dollars. 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. The program was sold by direct mail order for $49.95, without going through established sales channels (retailers or resellers). Unlike some other development tools, Turbo Pascal disks had no. Turbo Pascal came with the famous 'Book License': 'You must treat this software just like a book. [it] may be used by any number of people.
May be freely moved from one computer location to another, so long as there is no possibility of it being used at one location while it's being used at another.' Reception [ ] of wrote in February 1984 that Turbo Pascal 'comes close to what I think the computer industry is headed for: well documented, standard, plenty of good features, and a reasonable price'. Pournelle disliked the requirement to buy another license to distribute binaries, but noted that 'it turns out not to be a lot more. Borland only wants another $100' more than the $49.95 base price, and that 'my first impression of Turbo is that it's probably worth $149.95. It looks to do everything with the Speed Programming Package does, and maybe even do it faster and better'. He reported in July that, according to Kahn, IBM had refused to resell Turbo Pascal unless the price was at least $200; Pournelle noted that 'Turbo is much better than the Pascal IBM sells', and unlike the latter was compatible with the.
Three BYTE reviewers praised Turbo Pascal in the same issue. One called the DOS version 'without doubt, the best software value I have ever purchased', and another called the CP/M version 'an excellent product. [Borland] deserves praise for this high-value product'. The third stated that it was 'not a good compiler for developing massive applications', but added that it was greatly superior to, the programming language usually associated with home computers at the time.
He concluded that Turbo Pascal was 'a bargain that shouldn't be passed up'. Despite finding what it described as 'a serious bug' in version 3.0, and decreased compatibility with, the magazine in February 1986 stated that 'it is hard to avoid recommending Turbo to anyone who wants to program in Pascal', citing improved speed and graphic routines. When reviewing four other Pascal compilers in December 1986, BYTE described Turbo Pascal as 'practical and attractive to programmers at all levels of expertise'. Also praised the language in the magazine, stating in August 1985 that Turbo Pascal 'is best known for its small size, incredible compile speeds, and fast execution times'. He noted that the software's quality and low price had been especially surprising after the ' fiasco', and stated that even at the new higher $69.95 price, version 3.0 was 'probably still the best software deal on the market'. Was similarly complimentary in November 1984, stating that 'nothing like Turbo Pascal has ever existed for PC-DOS before'.
It praised the software's low price, speed, unusually good documentation for a compiler, and noted the existence of many utilities from other companies that hoped to benefit from Turbo Pascal's popularity. The review stated that the IDE that simplified the edit-compile-run-debug loop made Turbo Pascal accessible to new programmers like BASIC. BYTE in 1989 listed Turbo C and Turbo Pascal as among the 'Distinction' winners of the BYTE Awards. Citing their user interface and continued emphasis on speed, the magazine stated that 'for rapid prototyping there's not much better'. In the same issue Pournelle again praised version 4.0 and 5.0 of Turbo Pascal.
Citing as 'a good example of how complex a program you can write in Pascal', and the many libraries available from Borland and other developers, he wrote 'I am more and more convinced that Turbo Pascal is the programming language of choice for people who are more interested in what they want the machine to do than in how to make that happen. Turbo Pascal may be neither as elegant nor as portable as C, but it's sure less obscure. I think it may well be the language for the rest of us'. Borland sold about 250,000 copies of Turbo Pascal in two years, which Webster described as 'an amazing figure for a computer language'. He reported six months later that the figure had risen to 'more than 400,000 copies in a marketplace that had been estimated as having only 30,000 potential buyers'.

• Chapman, Merrill R. Borland made its debut in the industry in a big way with the release of Turbo Pascal in November 1983. Turbo Pascal was a port to DOS and CP/M of Anders Hejlsberg's COMPAS Pascal, and it was released by Borland at a price that seemed amazing at that time: $49.95, about one-tenth the price of comparable products. • Wallace, James; Erickson, Jim (1992).
