once you do this, i'm pretty sure the value of y is no longer in OP6. if u
want to save it, you need to push it onto the floating point stack.

so when u do this, you're not getting anything to move. that might be why
u have the overflow error. not sure though.

you could use _convop1 (not sure of the equate). it puts the floating
point number in op1 in de. i think that's exactly what you want.
sometimes, though, i get problems using it because de is 2 bytes, and the
ops are 11.
I hope this helps. What exactly is the prog supposed to do? i can't tell.
thanx.

Of course, Ankh-Morpork's citizens had always claimed that the river water
was incredibly pure. Any water that had passed through so many kidneys,
they reasoned, had to be very pure indeed.
