Regnecentralen was a semi-academic computer designer and manufacturer established by the Academy of Technical Sciences (Akademiet for de Tekniske Videnskaber, ATV) in 1955.

They developed a series of ALGOL 60 dialects named for the computers for which they were made. The second of these, Peter Naur's GIER ALGOL, was a design masterpiece and hugely influential in the history of programming

These details come from "RC4000, RC8000 and RC9000" below

Algol 1 was DASK ALGOL
Algol 2 - Algol 4 was GIER ALGOL
Algol 5 was for the RC4000
Algol 6 (appr. 1970) featured "field" data types and records, and the "long" data type (48-bit integer).

Algol 7 extended the language syntax with while-statements and repeat-until loops, and introduced "context records", a mechanism to support multi-user applications.

Algol 8 introduced support for real coroutine programming with the "activity" concept, including separate stacks and a very nice integration with the Algol I/O system.

The current version is called "Algol 8 Version 2". Many other features and enhancements than those mentioned above has been added over the years, and the run-time library has grown similarly.
