Extract wave scaling in a new wave

Hi,
I would copy the wave scaling of a wave (waveY) in a new wave (waveX)
I try to use:

Duplicate waveY.x waveX

but it doen't work
Can you help me?
thanks
thanks, but "CopyScales" trasfer scaling information from one wave to another wave.
I would extract (copy) the scaling information from one wave (waveY) and paste it into another wave (waveX).

for example:
waveX.d=waveY.x
but this comand doesn't work.
