Pascal is a computer language that was designed for teaching purposes. It makes extensive use of function and subroutine calls and allows code do be written in a very "readable" manner. Pascal is one of the precursors of the arguably most successful programming language C. Many people learned programming with Pascal, and a good deal of code exists that was written in this language. In recent times, Pascal has been extended a great deal, and with those extensions, the language can compete with more modern programming languages such as C/C++ or Java. We provide a Pascal compiler to enable those of our users who have "legacy code" in Pascal, or want to use modern programming techniques without having to learn a new programming language. However, Pascal is not supported as such by Sun/Solaris or IBM/AIX, i.e. there is no native Pascal compiler for our systems. Instead we use a portable public-domain compiler.
