    I guess... But as long as EQU and CBLOCK can be used in a
    program that also uses RES, the block isn't really "allocated";
    it's just protected from reuse by other RES directives, in the
    same way that registers named using CBLOCK can be kept from
    being renamed by other CBLOCK directives.  

    This is in contrast to what I think of as "real" allocation...
    Which would be the sort of thing you see in high-level
    languages, where (generally speaking) once a variable name is
    declared/used, other variable names will never be assigned to
    the same RAM. 

    I see what you mean, though.
