How do I pass a variable through multiple inner functions in KDB?

I’ve got a function peg:

  peg: {{$[abs[log x%y]>0.06;y;x]} scan x} 

The 0.06 is a parameter that I’d like to pass to peg from the outside, so I can do something like 0.06 peg x.

What’s a clean way of passing this variable through?

>Solution :

You could rewrite the function to add explicit variables so you can keep the local variable names as x and y. Below I’ve added a new argument v for the value you want to pass.

peg: {[v;x]{[v;x;y]$[abs[log x%y]>v;y;x]}[v] scan x}

peg[0.06;x]

I don’t think there’s any other easy way to do this.
