Maybe I am misinterpreting the question. But the Parallax assembler has the
DS (Define Space) directive which has an argument that allows you to specify
the number of locations needed. I use it like this:

;************************
;             RAM
;************************
                                ORG RAM

FLAGS                DS    1            ; 1 location, 8-bit value
TMRCTL            DS    1
MSG_TIMER    DS    2            ; 2 locations, 16-bit value
MSG_BUFF       DS    8            ; 8 locations

The assembler then assigns addresses starting at RAM and allocates the
requested number of locations for each variable in succession.

Not sure if that's what you were asking, but thought I'd throw it out
there...
