400,000 copies in a marketplace that had been estimated as having only 30,000 potential buyers". Jerry Pournelle 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". He 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 " more than the base price, and that "my first impression of Turbo is that it's probably worth . It looks to do everything MT+ with the Speed Programming Package does, and maybe even do it faster and better". Pournelle reported in July that, according to Kahn, IBM had refused to resell Turbo Pascal unless the price was at least ; Pournelle noted that "Turbo is much better than the Pascal IBM sells", and unlike the latter was compatible with the IBM PCjr. Three Byte reviewers praised Turbo Pascal in the same issue, calling the DOS version "without doubt, the best software value I have ever purchased" and the CP/M version "an excellent product" for which "[Borland] deserves praise". Despite finding what "a serious bug" in version 3.0, and decreased compatibility with PC clones, Byte 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, the magazine described Turbo Pascal as "practical and attractive to programmers at all levels of expertise". Webster also praised the language, 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 was especially surprising after the "JRT Pascal fiasco", and stated that even at the new higher price, version 3.0 was "probably still the best software deal on the market". PC Magazine 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, and unusually good documentation for a compiler, and noted the existence of many utilities for Turbo Pascal from other companies. The review stated that the IDE that simplified the edit-compile-run-debug loop made Turbo Pascal accessible, like BASIC, to new programmers. Byte in 1989 listed Turbo C and Turbo Pascal
