| -- other than those defined in package Standard. Names is a string with a |
| -- lower bound of 1 containing the characters of all the enumeration |
| -- literals concatenated together in sequence. Indexes is the address of an |
| -- array of type array (0 .. N) of Natural_8, where N is the number of |
| -- enumeration literals in the type. The Indexes values are the starting |
| -- subscript of each enumeration literal, indexed by Pos values, with an |
| -- extra entry at the end containing Names'Length + 1. The reason that |
| -- Indexes is passed by address is that the actual type is created on the |
| -- fly by the expander. The value returned is the desired 'Image value. |
