I'm sure that was the original intent, which I think is even still mentioned
in the manual.  However that was before relocatable mode and the linker
existed.

I'm trying to keep things simple in today's world where there has long been
relocatable mode and the RES directive.  That's why I say CBLOCK is for
enumerated constants and RES is for variables.  This should make it more
clear for those that might get confused, and also doesn't even consider
absolute mode as a option.  Today the only excuse for absolute mode is
having to do maintenence on archaic code, and even then converting it to
absolute mode would be a good idea before making any changes.
