Re: obsolete ascii? (for language lawyers)

Thanks to John Herro,  David C. Hoos, Sr.,  Ted Dennison.
I am afraid I did not explain my question precisely enough.
With Ada95 we have a quite better type character, but
I can't see any reason why i should not have the possibility
to directly write down e.g. the bel-character, the ff-character,
the cr-character, the esc-character etc. etc. as a simple identifier,
the comfort of which will be removed as soon as the
'obsolete' package ascii will be removed!
We even cannot write something like character'(bel) or the like.
Sort of latin1.bel could do it? 
Are there better ideas? Or did I miss a given feature?
