A self-defining term lets you specify a value explicitly. With self-defining terms, you can also specify decimal, binary, hexadecimal, or character data. If the DBCS assembler option is specified, you can specify a graphic self-defining term that contains pure double-byte data, or include double-byte data in character self-defining terms. These terms have absolute values and can be used as absolute terms in expressions to represent bit configurations, absolute addresses, displacements, length or other modifiers, or duplication factors.
