=== Pascal === As with C, the ; used by itself can be used as a null statement in [[Pascal (programming language)|Pascal]]. In fact, due to the specification of the language, in a BEGIN / END block, the semicolon is optional before the END statement, thus a semicolon used there is superfluous. Also, a block consisting of <code> BEGIN END;</code> may be used as a placeholder to indicate no action, even if placed inside another BEGIN / END block.
