David,

I made the assumption he needed to convert ascii strings to numbers.  That
might have been incorrect.   Often, when teaching Ada, I find that this kind
of question, when posed by someone from a C/C++ background, is not really
about the one-to-one correspondence between the character name and the
numeric ASCII value, but rather about making numbers from strings and
vice-versa.
