Unlike some other development tools, Turbo Pascal disks had no copy protection. Turbo Pascal came with the "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."[8]
Version 2, released a few months later on 17 April 1984, was an incremental improvement to the original Turbo Pascal, to the point that the reference manual was at first identical to version 1's, down to having 1983 as the copyright date on some of the compiler's sample output, but had a separate "Addendum to Reference Manual: Version 2.0 and 8087 Supplement" manual with separate page numbering.[32] Additions included an overlay system, where separate overlay procedures would be automatically swapped from disk into a reserved space in memory. This memory was part of the 64kB RAM used by the program's code, and was automatically the size of the largest overlay procedure.[32] Overlay procedures could include overlay sections themselves, but unless a RAM disk was used, the resulting disk swapping could be slow. 2.0 also added the Dispose procedure to manage the heap, allowing individual dynamic variables to be freed, as an alternative to the more primitive 'Mark/Release' system and increased compatibility with WordStar commands plus use of the numeric keypad on the IBM PC and compatibles.[32] Such PCs also had new text window and CGA graphics mode commands as well as being able to use the PC's speaker for tones. Finally, DOS and CP/M-86 machines with an 8087 maths coprocessor (or later compatible) had an alternative TURBO-87 compiler available to purchase.[32] It supported the 8087's long real data types with a range of 1.67E-307 to 1.67E+308 to 14 significant figure precision but with a much greater processing speed. The manual notes that although source code for the Turbo Pascal's software real data types offering a range of 1E-63 to 1E+63 to 11 significant figures, these were incompatible at a binary level: as well as having a much larger range, the software reals took six bytes in memory and the 8087 ones were eight.
free download software turbo pascal 7.0 13
Borland released several versions of Turbo Pascal as freeware after they became "antique software" (abandonware),[42] with 1.0 for DOS on 1 February 2000, 3.02 on 10 February 2000, 5.5 on 21 February 2002, Turbo Pascal 7.01 French version in year 2000.[43] Most of the downloads are still available on the successor website of Embarcadero Technologies.[2][3][4]
Some lecturers[who?] prefer to use Borland Pascal 7 or Turbo Pascal 5.5 because of its simplicity in comparison to more modern IDEs such as Microsoft Visual Studio or Borland JBuilder, so it introduces students unfamiliar with computing to common tasks such as using the keyboard and keyboard shortcuts (TP 5.5 has no mouse support), familiarises them with DOS commands (which are largely the same as those of Microsoft Windows's command prompt), and lets them write programs without spending a lot of effort on getting the environment to work. TP 5.5 is available as a free download from Borland.[42][43]
I loved turbo pascal 5I used others of course 3, 7 come to mind but 5 was the one which I really lovedThe compiler and all my source code I could carry around in my pocket (on a 3.5 inch floppy disk)I built 3D graphics in real time among a lot of other programs and had a great time using it.
