![]() ![]() New operator extensions to support SIMD programming - Type system extensions to support scientific and image processing - Many of the features of ISO extended Pascal (see ) in particular - Turbo Pascal features: Units, Strings, Turbo Pascal style file operations A comparison with other languages and implementation details are given in Vector Pascal an Array Language (). These extensions translate to the SIMD instructions of the Sandybridge and P4 etc. These are derived from APL and similar to the extensions provided in Fortran90. Free Pascal 3.2.2 is currently available for the following platforms: - Linux-i386 - Linux-x8664 (amd64) - Linux-powerpc - Linux-sparc - Linux-ARM - Win32-i386 (2000/XP, WinNT or later) - Win64-x8664 (XP or later) - Wince-ARM (cross compiled from win32-i386) - FreeBSD-i386 - FreeBSD-x8664 - Mac OS X/Darwin for PowerPC (32 and 64 bit) - Mac OS. Vector Pascal is an extended Pascal incorporating: - Unicode support - Vector Pascal extensions aimed at vector processing. Usually commercial software or games are produced for sale or to serve a commercial purpose."This manual describes the Glasgow Pascal Compiler which supports vector extensions similar to those developed by Turner and Formella, extensions introduced in ISO Extended Pascal and some new extensions. Even though, most trial software products are only time-limited some also have feature limitations. After that trial period (usually 15 to 90 days) the user can decide whether to buy the software or not. Trial software allows the user to evaluate the software for a limited amount of time. Demos are usually not time-limited (like Trial software) but the functionality is limited. In some cases, all the functionality is disabled until the license is purchased. Demoĭemo programs have a limited functionality for free, but charge for an advanced set of features or for the removal of advertisements from the program's interfaces. In some cases, ads may be show to the users. Basically, a product is offered Free to Play (Freemium) and the user can decide if he wants to pay the money (Premium) for additional features, services, virtual or physical goods that expand the functionality of the game. This license is commonly used for video games and it allows users to download and play the game for free. There are many different open source licenses but they all must comply with the Open Source Definition - in brief: the software can be freely used, modified and shared. Programs released under this license can be used at no cost for both personal and commercial purposes. Open Source software is software with source code that anyone can inspect, modify or enhance. Freeware products can be used free of charge for both personal and professional (commercial use).
