A label in a programming language is a sequence of characters that identifies a location within source code. In most languages labels take the form of an identifier often followed by a punctuation character (e.g. a colon). In many high level programming languages the purpose of a label is to act as the destination of a GOTO statement. In assembly language labels can be used anywhere an address can (for example as the operand of a JMP or MOV instruction).
