newbie problem

[Graeme Wallace <Dizzy@interact.net.au>]

If I want to get user input for my program in the form of a  string of
undefined length, how do I do so ?  If I set the string length to, say:

help_me_please : String(1..20);

I seem to be stuck with a string exactly that size.  What is the
variable assignment which allows the actual length of the user input to
determine the length of the string which the io system
(ada.text_io.)gets ?

Thankyou.
