Character'pos('8') will return the integer value 56.
Integer'image("8") will return the integer value 8. Integer'image("88") will
return the integer value 88, Integer'image("888") will..., well, you get the
idea.
I suspect the second is what you are asking for. It would be a good idea to
look through annex K of the Ada LRM ( http://www.adahome.com/rm95/rm9x-K.html
). There are all sorts of goodies in there for you!
