Finding max and min of a numbers' list stored in macro

Dear All,

I am looking for a solution to find maximum and minimum numbers stored in a local/global macro. For example, I define a local as follows:

Code:

local x 1 2 3 4 5 9

I want to store maximum value of above list (i.e. 9) in another local as follows:

Code:

local y = max(`x')

Kindly help me do this.

Best
Amit
