Hi Steve, I think msg.patch looks good. I'd like to postpone the other changes until the "shrink factor" in DEM is understood.

I decided that it was best to leave in 'byte get()' as there are many places where a byte is used to hold the result and a cast would be needed for 'int get1()'. The tests pass, but there is more scope for getting this patch wrong so needs some good testing. Also display project would have to be patched to match. ..Steve
