Subject: obsolete ascii? (for language lawyers)
Date: 1999/06/29
Date: 1999-06-29T00:00:00+00:00	[thread overview]
Message-ID: <7las7v$5p0$1@infosun2.rus.uni-stuttgart.de> (raw)

LRM A.1(36) states an obsolete package ASCII.

now look at my example:

                     with text_io;
procedure hello is
   bell : character := character'val(7);
 --bell2 : character := bel;  -- is not allowed  :-(
begin
   text_io.put_line ("Hallo Welt..." & ascii.bel & bell);
   end hello;

What is the reason for this degradation?
Why then (zum Kuckuck!) is package ascii declared obsolete?

------------------

An additional remark:
text_io.put_line(ascii.bel); is not allowed,
because put_line (in contrast to put) does not
allow single characters as parameters.
This is hard to explain to a beginner and
therefore a nasty design decision for text_io:
having to obey to special cases.
Moreover, one could never say:
'put_line' is a combined 'put' and a 'new_line',
for the sake of simplicity.
