Where can I find documentation for the Select/When/Otherwise statement?

Question

I love using the Select/When/Otherwise statement in the data step, but my code always needs debugged before it will run properly. I never can remember the exact syntax required and SAS doesn't have very good documentation for it. (I actually can't find any mention of it except in the SCL documentation). Sometime it's because I put a semicolon after the When statements or forget that I need a Do block. Is this feature officially unsupported? If not then why isn't it documented?
