Dear Statalist,

I have list of items create by -levelsof- macro and I would like to select
three items from that list at random and for them to be non-repetitive
(i.e. each one can appear only once in the selection).

Lets say I have a list -local list "one two three four five six"- and I
would like to get
local random1 =
local random2 =
local random3 =

where each one is a random selection from the local list and each item
appears at max once.
I would appreciate any help on how to do that.

Thank you!
Tomas
