Command -- the class of all commands

Synopsis

Description

A command behaves as a function does if it is followed by an adjacent expression that can serve as its argument or argument list. In addition, if it appears as the value of an expression typed by the user at top level (i.e., not in a file), then it gets executed with empty argument list.
