Converting Type Characters to type string

[jedivaughn <jedivaughn14@gmail.com>]

Hi,
 I am looking for a way to convert a group of characters to a string.
For the program I am writing I am having the user input a group of
characters and comparing them. But I also need the characters in the
form of a string later on so I can use

int := Integer'Value(str);

How would I go about doing this? From the little bit I've founding
searching this I think I may need to use the ada.character.handeling
package. But on looking through this

I can't find out how to do what I want. I am fairly new to Ada so if
you could give some examples of how you would do this I would really
appreciate it.

Thanks,
John
