    Martin:

    It appears that there's no functional difference between
    CONSTANT and EQU; the main difference seems to be that you can
    define multiple CONSTANTs on one line, e.g.:

        CONSTANT X=1,Y=2,Z=3

    Here there's DEFINITELY no functional difference, but VARIABLE
    allows you to declare a symbol without initializing it, e.g.:

        VARIABLE X,Y,Z

    is perfectly legal; X, Y, and Z can later be defined (and
    redefined) to whatever values you like.

    Either of those will work.
