Identifiers

An identifier is a technical term for a name. Identifiers are used for line labels, variable names, and constant aliases. An identifier is any sequence of letters, digits, and underscores, although it must not start with a digit. Identifiers are not case sensitive, therefore label, LABEL, and Label are all treated as equivalent. Because of the limitations in the assembler program, identifiers can not be larger than 32 characters in length.
