No FAQ? A stupid question, then?

No FAQ? A stupid question, then?

[Ricardo Palomares Martínez]

    Greetings:

    Sorry if this is a FAQ, but I have been watching the news group for
more than a week and have not found the FAQ posted, nor references to it
in the subjects, and I'm in a bit of hurry.

    My problem is simple: I need to get the string expression of integer
and real numbers (the usual Str(number) of other languages), but I'm
unable (that wouldn't be surprising if you did know me :-) ) to get the
equivalent function looking around the Ada reference (the HTML files
which came with GNAT 3.07 for MS-DOS). So, I ask for an answer to any of
the following questions:


   * Is there any place where I can find a reference similar to the HLP
     files included in products like Delphi or Visual Basic (ie, where I
     can look for functions or procedures without having to know the
     packages hierarchy)?
   * Is there such a function like the ones I'm looking for in Ada95?

    Thanks a lot in advance. One more thing: while I will watch the news
group, my news server has been a bit inestable in the last weeks, so I
would appreciate a mail CC. I will post a summary of the answers in the
news group if anybody requests it to me. Thanks again.

The attribute T'Image returns the string form of a number, ie

   S : String := Integer'Image (42);

You can go the other way, and get the value that corresponds to a
string:

   I : Integer := Integer'Value ("42");

For your general Ada information you might try http://www.adahome.com/
which has quite a lot of information including FAQs

There is a windows help version of the RM95 that that comes with Ada GIDE (a
free IDE for GNAT). You can find it on the PAL. You can also find an on-line
HTML version at www.adahome.com.

    In the end, my news servers seems to work well and I have seen the
answers from Mathew Heaney, Brian Orpin, Stuart Palin and David Botton.
Thanks a lot to all of you for your valuable answers. It seems that I'm the
responsible for a new section in the David Botton's Web Page (Language and
Technique Examples -> Basic) :-) Thanks again.

  This exact question was answered here a couple of weeks ago, and I
see it's been answered again.  www.dejanews.com keeps comp.lang.ada
and would be a good place to look for this sort of thing.  Using an
attribute is admittedly non-obvious, but, by analogy to sprintf, you
could look at ada.text_io and see that one form of Put takes a string,
rather than a file, as its destination.
