COMAL
open-in-new
<p>COMAL (<i>Common Algorithmic Language</i>) is a computer <a href="/facts/Programming_language/cWTYbgWa">programming language</a> developed in <a href="/facts/Denmark/KVtykzsw">Denmark</a> by Børge R. Christensen and Benedict Løfstedt and originally released in 1975. It was based on the <a href="/facts/BASIC/VYMl5TmA">BASIC</a> <a href="/facts/Programming_language/cWTYbgWa">programming language</a>, adding multi-line statements and well-defined <a href="/facts/Subroutine/9vFJrg0A">subroutines</a> among other additions. </p><p>COMAL was originally written for <a href="/facts/Minicomputer/g8hvpQxe">minicomputers</a>, but was small enough to run on early <a href="/facts/Microcomputer/ETW22UTv">microcomputers</a> as well. It is one of the few <a href="/facts/Structured_programming/zA8b8dP1">structured programming</a> languages that were available for and comfortably usable on <a href="/facts/8-bit/2CkhLNoH">8-bit</a> <a href="/facts/Home_computer/CDEPVd1T">home computers</a>. </p><p>"COMAL Kernel Syntax & Semantics" contains the formal definition of the language. Further extensions are common to many implementations. </p>
