Standard Pascal was a nice language with terrible limitations: Pascal programs could not open files by name, could barely handle strings and could only pass arrays of predetermined sizes to functions. BrianKernighan famously described Pascal's problems in [Why Pascal is Not My Favorite Programming Language |http://www.lysator.liu.se/c/bwk-on-pascal.html]. It has to be noted that NicolasWirth had already addressed most of Pascal's problems in his follow-up language [Modula2] ''before'' BrianKernighan wrote this paper. In some places BrianKernighan seems to be just complaining that Pascal is not [C]. At any rate, these limitations meant that Pascal splintered into dialects as people hacked in missing features in incompatible ways. [C] did not have this problem, so it gradually took over from the Pascal dialects.

the source code to the original Pascal compiler. It's educational to read just as an extended critique
of a non-trivial program

-The most successful Pascal dialect has been Borland's TurboPascal. Further extended with [Modula2]-like modules and [C++]-like [OOP] it became [Delphi], which exists on [Linux] nowadays under the name [Kylix].

* [GNU Pascal | http://www.gnu-pascal.de/]
* [Free Pascal | http://www.freepascal.org/]

you can get a free copy of TurboPascal 5
