David, 

An enumeration type declaration specifies a list of distinct 
items, enclosed in parentheses. The items are identifiers or 
character literals. In either case the legal values of the 
type are referred to as "enumeration literals." Each of these 
values has a "position number" corresponding to its position 
in the list  Enumeration types have attributes  T'First, T'Last, 
T'Range, T'Pred, T'Succ, T'Min, T'Max, T'Image, T'Wide_Image, 
T'Value, T'Wide_Value, T'Pos, and T'Val

Numeric types specify sets of numerical values and include 
integer types, floating-point types, and fixed-point types. 
Generally speaking, numeric types have the same attributes as 
enumeration types. However, floating-point and fixed-point 
types do not have the T'Pos and T'Val attributes. Some numeric 
types have additional attributes. For example, fixed-point types 
have the attributes T'Delta, and T'Small.

(Congratulations on the proper spelling of Ada, and good 
luck with our favorite language. :-)
