|(language)||Modula-2 - A high-level programming language designed by
Niklaus Wirth at ETH in 1978. It is a derivative of
Pascal with well-defined interfaces between modules, and
facilities for parallel computation. Modula-2 was developed
as the system language for the Lilith workstation.|
The central concept is the module which may be used to encapsulate a set of related subprograms and data structures, and restrict their visibility from other portions of the program. Each module has a definition part giving the interface, and an implementation part.
The language provides limited single-processor concurrency (monitors, coroutines and explicit transfer of control) and hardware access (absolute addresses and interrupts). It uses name equivalence.
