coercing an integer to a string

[dummy@e.mail (Emmanuel M. D�carie)]

Hello, 

I need 2 functions.

Function 1 will take for input an integer and will return the number as a
string.

Function 2 will reverse this action, i.e. will take a string that contains
a integer and will return an integer.

Can anybody suggest me a way to do this, or point me to a faq.

I'm just starting with Ada, and I can find anything on this in "Ada 95
From the Beginning" and in "Ada 95 Problem Solving and Program Design.

Thanks.
