Unfortunately, no. I have to use it with something like

   dq  @@R0,@@R1,@@R2,@@R3

where the @@nn are labels (this is done to select the right jump at
run time).

I thought to use hexadecimal code to replace the mnemonic "dq" itself
but 1) I don't know its code and 2) I am not even sure it would work.
