If I saw this in code, I would be unhappy. Mysterious constants
have no place appearing like this. Better style is

  Home_Cursor constant String := Ascii.ESC & "[0p";
  --  Sequence for homing cursor

  Ada.Text_IO.Put (Home_Cursor & "hello there!");

Note that Ada requires that the concatenation be done at
compile time, so no inefficiency is involved.

Note: I don;t know if this is the home cursor command, I
just use this for illustrating the style.
