COMAL (COMmon Algoritmic Language) is a computerprogramming language developed in Denmark
by Benedict Loefstedt and Borge Christensen in 1973.
It was really a mixture of the BASIC and Pascal programming languages, which was meant to introduce structured programming elements in an environment where BASIC would normally be used. The "COMAL 80 PROGRAMMING LANGUAGE" report contained the definition of the language.
