[amibroker] Passing a variable into the Ref() function

[chorlton_c_hardy]

Hello All,

With regard to the Ref() function in AB, is there any way to pass a 
variable into it rather than using a specific value?

For example:

Rather than writing Ref(Close,-10), I want to write Ref(Close,-x) where 
x has been defined earlier in my code.


Thanks in advance,

Chorlton
