Hello,

I'm programming with Ada95 on Solaris 2 and I'm a beginner. I would like some information about using the "+" symbol like a pointer operator for string. 
So I've created the following example.

s: string;
.
.
.
procedure new_String(s_ptr:String_Ptr) is
begin
.
.
.
end new_String;

.
.
.
s:="hello";
new_String(+s);

Could you explain me such a mecanism because I don't understand it. Do I need
to import a special librairy. Could tell me which one.
Thank you an advance for your help.
