You were attempting to assign a 9-Character String to an 80-Character String. 
When assigning arrays, both sides need to be the same size.

The Get_Line function is best suited to initializing a String object, or 
providing a value to another subprogram:

S1 : constant String := Ada.Text_IO.Get_Line;

S2 : String := Ada.Text_IO.Get_Line;

Ada.Text_IO.Put_Line (Item => Ada.Text_IO.Get_Line);
