The Modula programming language is a descendant of the Pascal language. It was developed in Switzerland, at ETH Zurich, in the mid-1970s by Niklaus Wirth, the same person who designed Pascal. The main innovation of Modula over Pascal is a module system, used for grouping sets of related declarations into program units; hence the name Modula. The language is defined in a report by Wirth called Modula. A language for modular multiprogramming published 1976.[1]

Modula was first implemented by Wirth on a PDP-11. Very soon, other implementations followed, most importantly, the compilers developed for University of York Modula, and one at Philips Laboratories named PL Modula, which generated code for the LSI-11 microprocessor.

The development of Modula was discontinued soon after its publication. Wirth then concentrated his efforts on Modula's successor, Modula-2.

Equal incircles theorem

On rays from a point to a line, with equal inscribed circles between adjacent rays If the blue circles are equal, the green circles are also equal. In geometry, the equal incircles theorem derives from a Japanese Sangaku, and pertains to the following construction: a series of rays are drawn from a given point to a given line such that the inscribed circles of the triangles formed by adjacent rays and the base line are equal. In the illustration the equal blue circles define the spacing betwe...
