I wrote a Integer as an example, i could add Natural also, for this example there are not difference.

I'm using 'Range to go through all the positions in enumeration.

I tried to use Ada.Unchecked_Conversion and i got obtain the values for the position. but as you told me, if i use 'post (), the number of the list start in 0.
