John Herro said, talking of the question about dealing with a variable
length string value returned

<<Does anyone have other solutions?
>>

Most certainly! The normal solutoin is just to declare a local variable
and initialize it with the returned value:

   x : string := f(x);

That's straightforward. If you want to use pointers, then you can use

   type x is access all string;

   xv : x;

   xv := new String'(f(x));

These seems straightforward, so I am not quite sure I understand John
Herro's reference to "minor annoyance". In a language designed NOT to
require default heap allocation, the Ada semantics seem quite reasonable.
I also find John's suggested solutions unnecessarily complex (so perhaps
that's why he finds this so annoying :-)
