UniqueSet¶

A UniqueSet is a collection of any type in kOS. It doesn’t store items in any particular order and does not allow duplicate items. You can read more about sets on Wikipedia.

Usage example:

SET S TO UNIQUESET(1,2,3).
PRINT S:LENGTH. // will print 3
S:ADD(1). // 1 was already in the set so nothing happens
PRINT S:LENGTH. // will print 3 again
