Modula-2+ is a programming language descended from the Modula-2 language. It was developed at DEC Systems Research Center (SRC) and Acorn Computers Ltd Research Centre in Palo Alto, California. Modula-2+ is Modula-2 with exceptions and threads. The group who developed the language was led by P. Rovner in 1984.
Main differences with Modula-2:
Modula-2+ has been used to develop Topaz, an operating system for the DEC SRC Firefly Multiprocessor. Most Topaz applications were written in the Modula-2+ programming language which grew along with the development of the system. Also to build a programming environment for it in the Acorn Research Center ARC. The language has now completely disappeared but was of great influence to other programming languages such as Modula-3.
The original developers of Modula-2+ were both bought; Acorn by Olivetti and Digital Equipment Corporation by Compaq. Compaq itself was bought by Hewlett-Packard. Olivetti also sold the Olivetti Research Center and Olivetti Software Technology Laboratory (after bought Acorn ARC) to Oracle and was later absorbed by AT&T. DEC have made the SRC-reports available to the public.
