Not sure what this is called, but I saw it once, and need to do it again.

It's like a Boolean, you have a select list of options to choose from (in booleans case, it's only True or False) How do I create my own?

Like:
Dim k as CustomStatus
k = Stopped

Where CustomStatus can be set to one of the following only:
Stopped
Running
Waiting
Paused

Even if I knew what this is called I can research it, but I never used it before.
