A literal inside a enumeration is a discrete type so we can use attribute Image to find out which literal it is as text form. Notice that this prints out the same word as in the code (but in upper case). with Ada.Text_IO; use Ada.Text_IO; procedure Main is type Fruit is (Banana, Pear, Orang...

Attribute Image capitalizes all characters of enumeration literals. The function Case_Rule_For_Names applies upper case for the first character and makes the rest lower case. with Ada.Text_IO; use Ada.Text_IO; with Ada.Strings.Maps.Constants; use Ada.Strings.Maps.Constants; with Ada.Strings.Fixed...
