Sure: type Enum is (One, Two, Three); for Enum use (One => 1, Two => 2, Three => 4); type Rep_List is array (Enum) of Positive; Get_Rep : constant Rep_List := (One => 1, Two => 2, Three => 4); E : Enum := Enum'First; Rep : Positive := Get_Rep (E); If you mean a way built into the language, that's called Unchecked_Conversion. -- Jeff Carter "My legs are gray, my ears are gnarled, my eyes are old and bent."
