This one reads a line with no length limit:
function Get_Line return String is
Buffer : String (1..500); -- or whatever
Last : Natural;
begin
Get_Line (Buffer, Last);
if Last < Buffer'Last then
return Buffer (1..Last);
else
return Buffer & Get_Line;
end if;
end Get_Line;
In most cases, there will be only one call, while having no upper limit.
The size of the buffer is just a matter of optimization.
