Label (Computer Science)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. 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. 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.
