<CORE>
CREATE a new word with runtime ((CONSTANT))
so that the value placed here is returned everytime
the constant's name is used in code. See VALUE
for constant-like names that are expected to change
during execution of the program. In a ROM-able
forth the CONSTANT-value may get into a shared
ROM-area and is never copied to a RAM-address.
