# QL Pascal

What is Pascal? It is the name of a French mathematician and philosopher (Blaise, P., 1623-1662}, but it is also the name of a high-level computer language. This lenguage was developed in 1968 for the main purpose of teaching computer programming. Since that time it has become quite popular as an all-purpose language for use on microcomputers. It is a compiled language – that is, programs are first written as a text file, and then converted to a program that will run. The conversion is performed by a special program, called a “compiler”. Usually run-time procedures must be also be linked with the compiled code-file to complete the process. The final result is a machine code program, that can loaded and run, on the QL, by typing in the Qdos command “exec drive & filename>”. Pascal compiler’s ate available for all the T/S computers. Three of them have been written for the QLI.
