Thanks for that reply and clarification Mark.  That definitely helps.  

Well, I had a feeling that, assuming this was an actual limitation of the HDL syntax, that chapter 1's 16-bit de-multiplexer may come in handy here.   Using zx as a type
of 'selection' bit and using 'true' / 'false' to set banks of inputs to the DMux to one or the other value set using zx to control which one of these banks of 16-bits gets out may be the ticket.   Perhaps that'll be the quick solution you are alluding to....  ;-)

Thanks again!
