Constants defined by the DC instruction are assembled into an object module at the location at which the instruction is specified. However, the type of constant being defined, and the presence or absence of a length modifier, determines whether the constant is to be aligned on a particular storage boundary or not (see Alignment of constants).
Symbolic Addresses of Constants: The value of the symbol that names the DC instruction is the address of the first byte (after alignment) of the first or only constant.
