There's _setxxop1 and _setxxxxop2, but im sure youre familiar with those 
already.  For a way to put DE into OP1, try this...

push de
call _zeroop1
pop de
ld (OP1+0), e
ld (OP1+1), d

although the problem there is that I am not sure of the order D and E should 
be loaded into OP1, perhaps someone else knows that. Another problem is it 
could destroy many other registers, im not sure of which either, but maybe 
this process can help you. cya...
