  So Input_Line is of type String, and Arr is a different type.

  "Arr'()" says "the thing inside the parens is of type Arr".  But in fact
the thing inside the parens is not an Arr, but is a String.  So the
compiler quite rightly points out that it expected something of type Arr.
  Perhaps what you want is
subtype Arr is String;
which, since there are no special constraints, would in effect mean
that "Arr" is a synonym for "String".  Of course even easier is just
to forget about "Arr" entirely, and just use "String" where you now
have "Arr".

  If you want "n" to point to just the data read, and not the whole
256 characters, you want
   n:=new Arr'(Input_Line(Input_Line'first .. LAST));
