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 {module}s, 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}
({monitor}s, {coroutine}s and explicit transfer of control)
and hardware access ({absolute address}es and {interrupt}s).
It uses {name equivalence}.
