No, the dw opcodes are the wire level protocol, they are how data is
transferred at the request of the higher level operations but there is no
mechanism for using the high level APIs to then send low level OP codes
again.  That sounds like an inefficient strategy, you'd be turning a single
byte opcode into several bytes and a few instructions on the coco into
hundreds if not thousands by the time things were done.. there is probably
a better way to accomplish things.
