BAR (COMPUTER SCIENCE)

'Bar' is a metasyntactic variable used heavily in computer science to represent concepts abstractly and can be used to represent any part of a complicated system or idea including the data, variables, functions, and commands just to name a few. Bar is commonly used with the metavariables foo and foobar. The word ''bar'' as used in computer science has no meaning and is merely a commonly used logical representation that is used much like the letters 'X' and 'Y' in algebra.
Bar entered the english language as a neologism due to its popularity in describing concepts in computer science and continues to be popular in computer programming examples and pseudocode.
