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:
“The label of liberalism is hardly a sentence to public igominy: otherwise Bruce Springsteen would still be rehabilitating used Cadillacs in Asbury Park and Jane Fonda, for all we know, would be just another overweight housewife.”
—Barbara Ehrenreich (b. 1941)
