Algol-Genius, an Algol 60 implementation with features from COBOL, was the brainchild of Börje Langefors. In 1964, assembler was the dominant programming language, but Algol-Genius broke that trend among Datasaab D21 customers. Algol-Genius programs were still in production in the late nineties.

Chandra Low Energy Transmission Grating Spectrograph observations of Algol have been used to determine the abundances of C and N in the secondary star for the first time. In order to minimise errors arising from an uncertain coronal differential emission measure as a function of temperature, the analysis was performed relative to similar observations of an adopted “standard” star HR 1099. It is...

This report contains details of over 100 Algol 60 test programs available from NPL which can be used to validate a compiler. Interpreting the results of the tests requires a good knowledge of Algol 60.

Algol 68 is considerably more difficult to learn than Pascal, partly due to the unusual terminology of Algol 68, which has not been widely accepted. The defining document of Algol 68 is much more elaborate and precise than the Pascal Report, but is also much more difficult to understand than the shorter and less formal Pascal document. This applies, in particular, to the two-level context-sensi...

We present a systematic analysis of the four known large X-ray flares detected to date on the eclipsing binary system Algol, using an approach based on hydrodynamic simulations of decaying flaring loops including sustained heating. This method yields, for the large BeppoSAX Algol flare of Aug. 1997 (where a geometrical estimate of the size of the flaring region is available) a more reliable siz...

A simple Idealized Algol is considered, based on Reynolds's \essence of Algol." It is shown that observational equivalence in this language conservatively extends observational equivalence in its assignment-free functional sublanguage.
