Array help needed..

[devine]

Hi.  Kinda of a newbie to ada.  I have a array setup into which I want
to put words.  I keep getting a standard.integer error for this line:
Ada.Text_IO.Put(Item => Found(Word)), can someone please explain why I
am getting that error and how I can fix it?  I excluded the open file
code.

  Char : Character  
  Found : String(1..10) 

  TYPE CharArray IS ARRAY (1..80) of Character;
  Word : CharArray;

  LOOP
    EXIT WHEN Ada.Text_IO.End_Of_File(InData);
    LOOP
    Ada.Text_IO.Get(File => InData, Item => Char);
       IF Char IN 'a'..'z' THEN
       Ada.Text_IO.Put(Item => Found(Word));
       END IF;
    END LOOP;
  END LOOP; 

Thanks.

Found is an string of characters indexed by integers, right?  What you've
done is to try to use Word as an index which is an array of characters, not
an integer hence the message.  What are you trying to do?

You are putting characters by the look of it.

Because Word is not an integer. You have defined Found to be a
String(1..10), but Word is an array of characters. But I really don't
understand your code or what you try
to do. Is this an assignment?

I trying to do this.  Read a file, check to see if their are words in the
file and then put the words into an array.  So I used 'a'..'z' to get a
character so when it hits a space that would be the end of the word, it
would move to the next character after the space.

Consider these possibilities:

  1.  The words may have capital letters and apostrophes -- i.e.,
      characters that are not in 'a' .. 'z', 

  2.  The spaces between words may not just be single space characters --
      they may have multiple spaces, tabs, periods, commas, and other
      punctuation marks.

  3.  What about numbers? E.g., if you have the sentence "there were 375
      people present." -- is 375 a word?

You should loook at the procedure Ada.Strings.Fixed.Find_Token which
allows you to find tokens that include a particular group of characters,
or that exclude a particular list of characters.
