I didn't know that, but there's a lot I don't know about Haskell. It works great. Thanks!

What do I need to add to this Color enum type to print a list of them?

You can also easily print a list of /all/ of them. Regards, John scratch$ cat color.hs data Color     = Red     | Blue     | Green     | Yellow     | Orange     | Brown     | White     | Black   deriving (Show,Enum,Bounded) scratch$ ghci color.hs *Main> [minBound..maxBound] :: [Color] [Red,Blue,Green,Yellow,Orange,Brown,White,Black]
