The way to do this is to use a function that returns a String:
function Get_Line
(File : Ada.Text_Io.File_Type := Ada.Text_Io.Current_Input)
return String;
Help_Me_Please : String := Get_Line;
This will generally serve. You can obtain more flexibility at the price
of more complexity by converting the result of the function to a
variable-length string (Ada.Strings.Bounded or Ada.Strings.Unbounded).
