In computing, the name Short code (singular noun) refers to the language of the same name which was the first actually implemented language used for an electronic computing device. The technique used in programming the device involved using codes, usually called short codes (plural) which mapped to hardware functions. At the time, the language had to be 'hand coded' or simply put 'manually compiled' to machine code, rather than being able to parse it through a lexical analyser or compiler. The technique is named synonymously with pseudocodes, which can be confused with the highlevel language-independent algorithm 'language' representation. Short Code was the predecessor to Speedcoding, which extended Short Code by allowing for floating point calculations and code representation for the four calculation operators (* / + -?) Machine code or machine language is a system of instructions and data directly understandable by a computers central processing unit. ... Lexical analysis is the process of taking an input string of characters (such as the source code of a computer program) and producing a sequence of symbols called lexical tokens, or just tokens, which may be handled more easily by a parser. ... A diagram of the operation of a typical multi-language compiler. ... Pseudocodes can refer to the technique of using short codes, especially within the language with singular name Short Code, which was the first ever language developed for an electronic computing device. ...
