[gradsusr] Filter values

[Andrew Revering]

I figured out a way to exchange values on a grid by doing this.

 

'define v = re(value,0.037)'

'define mv = if(const(v,0,-u),<,30,0,const(v,0,-u))'

 

But that sets ALL values less than 30 to a value of 0 on the entire grid.
What I'd like to do is the same thing, but only for a portion of the grid.
Is there a way to constrict this to just check an area within x distance of
the center, but not change values outside of this center radius?
