Modula-2

language 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.
