COMAL (Common Algorithmic Language) is a computer programming language developed in Denmark by Benedict Løfstedt and Børge R. Christensen in 1973.  This archive is the .CRT version of COMAL 80 Rev 2.01 for the Commodore 64.  Here is a link to the manual.

This version of the archive includes some additional information about the cartridge, the complete 128k .bin that was then converted to the 64k .crt and a demo disk full of sample code.  Also of note is that this version is by "UniComal ApS" where the other version is "UniComal & Commodore".
