Yes, I can use an array, but I don't like it here. Actually I use the set as
a parameter for passing the values to a function, and most time I need only
one or two values to be passed. Only occasionally pass more values. So in
most time I have to ignore all other values or giving the dumb values except
one or two that I need. The program will look ugly. Don't you think so?

Is there any reason you can't use an array instead?
