Collection as out parameter in function - help required

Question

I am having a fucntion which returns 3 different values based on a given in parameter.
Now , I want to return these three values.
Instead of using three out parameters, how can I use a collection for returning the values.
Please tell me the best way in returing the multiple values(more than 3)
Thanks in advance
