whoa wait though....the problem l'm having is with getting the compiler to 
pass the register d2 as the "argument" for how high the sprite is supposed to 
be.  l can put in any decimal number in  place of d2 in the dc.w parts of 
sprite:, but putting %d2 there gives a "bad expression" error.
Down below,
    dc.w    %d2
is giving the error.

sprite(x,y,lines)
int x;
int y;
int lines;

    move.w 10(%sp),%d1
