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 the destination of a e.g. JMP. Also in Pascal and its derived variations. Some languages, such as Fortran and BASIC, support numeric labels. Labels are also used to identify an entry point into a compiled sequence of statements (e.g., during debugging).
Famous quotes containing the word label:
“... beauty, like ecstasy, has always been hostile to the commonplace. And the commonplace, under its popular label of the normal, has been the supreme authority for Homo sapiens since the days when he was probably arboreal.”
—Ellen Glasgow (1873–1945)
