What is Pascal?
Pascal is a general purpose computer programming language. It is very structured, and quite adequate for starters in computer programming.
Turbo Pascal has been the most used version of Pascal language for a long time. It was developed by Borland, for Dos operating System. Now it is more used a open source alternative, called Free Pascal, which is available for several operating systems.
Delphi is a visual development tool for Windows, created by Borland, based on Pascal language. Kylix is the Linux version of Delphi. Lazarus is an open source Delphi clone, available for Windows, Linux and other operating systems.

- Pascal tutorial (in Spanish), by Nacho Cabanes, (still not completed) hosted byaprendeAprogramar.com.
- Free Pascal (formerly FPK Pascal) is probably the best choice nowadays. It is a 32 bits free pascal compiler, mostly Turbo Pascal compatible, with several Delphi extensions. It has an Integrated Development Enviroment (IDE) similar to Turbo Pascal's. There are versions for Windows, Linux, OS/2 and other operating systems. You can find it at www.freepascal.org (version 2.0.4 available since august 2006).

Latest version is number 7, but Turbo Pascal 1 is available for download from Borland's site, as well as Turbo Pascal 3.02 and Turbo Pascal 5.5. Note: Turbo Pascal 7, the lastest version, does not work properly on current PCs (most Pentium II and above). It is the Runtime error 200. You can find more information about it at www.brain.uni-freiburg.de/ ~klaus/pascal/ runerr200.
- Delphi is a commercial product for Windows, created by Borland (you can also fin a free clone called Lazarus a bit later). Now and then, you can find evaluation versions in computing magazines or any "Personal Edition" in Borland's site, but it has not happened since long ago...
- Lazarus is a Delphi clone (for Linux, Windows and other systems) created over Free Pascal. Its site is www.lazarus.freepascal.org. It is still in beta stage, but quite usable. Version 0.9.22 available since 30-Mar-2007
- Chrome is an Object Pascal compiler for the .Net platform. There is a commercial version, which can be integrated in Visual Studio, but also a free version, which includes the command-line compiler. More details in www.chromesville.com
- Kylix was the Linux version of Delphi. A free version existed, but now it seems ti be discontinued (you cantry to search at Borland's site).
- GNU Pascal (GPC) is developed over the GCC compiler. More information and downloads: www.gnu-pascal.de.
- Dev-Pascal is a development environment, by Bloodshed, which can be used with Gnu Pascal or Free Pascal. The download including Free Pascal is near 8 Mb in size.
- Virtual Pascal. A 32 bits Pascal compiler for DOS y OS/2, with syntax and environment very similar to Pascal 7. Currently discontinued, but it can still be downloaded as a 25 MB Zip file at vpascal.ning.com
