Oh, really?

  if ((input = 'y') or (input = 'Y')) then
    begin
      writeln ('blah blah');
    end
  else if ((input = 'n') or (input = 'N')) then
    begin
      writeln ('blah');
    end
  else
    begin
      writeln ('Input invalid!');
    end;

  if input == 'y' || input = 'Y'
  {
      writeln ('blah blah');
  } else if input = 'n' || input = 'N'
  {
      writeln ('blah');
  } else
  {
      writeln ('Input invalid!');
  }

If you find Pascal easier to read, I would guess you have very special set of eyes.
