Edinburgh IMP

Edinburgh IMP is a development of ATLAS Autocode, initially developed around 1966-1969 at Edinburgh University, Scotland. IMP was a general-purpose programming language which was used heavily for systems programming.Expressively, IMP is extremely similar to Algol and includes all the Algol-style block structure, reserved keywords, and datatypes such as arrays and records. It adds to Algol-style languages a string type (akin to a flex array of char) and built-in operators for string manipulation and character handling.
