Mix of structured text language of IEC1131, and ISO Modula-2; optimized for the most common 8-bit controller, the Intel C51 core, mainly for Programmable Logic Controllers (PLCs), embedded controls.

The Association for Computing Machinery gave Wirth the prestigious Alan M. Turing Award in 1984: For developing a sequence of innovative computer languages, Euler, Algol-W, Modula, Pascal. Pascal has become pedagogically significant and has provided a foundation for future computer language, systems, and architectural research.

By Niklaus Wirth; Communications of the ACM, April 1971. Programming is usually taught by examples. Experience shows that the success of a programming course critically depends on the choice of these examples. Unfortunately, they are too often selected with the prime intent to demonstrate what a computer can do. Instead, a main criterion for selection should be their suitability to exhibit certain widely applicable techniques. [ACM]

Makes, sells several Wirth languages (Pascal, Modula-2, Oberon-2) for Java: run on Java virtual machine, compilers implemented in plain Java, can output Java sources or byte codes, directly import classes from any Java package.
