I'd like to add some comments which may be of some help for you. The expression andyfaff posted can be used in functions like:

Function Substact(a,b)
    Wave a,b
    a = a - b
End

You can do a simple assignment in the command window to achieve the same by typing this:
a = a - b
or shorter
a -= b
Note that this subtraction method doesn't make use of you eventual wave scaling.

I recommend that you read more about this in the 'Waveform Arithmetic and Assignments' chapter in the manual.
