  if myInteger.TryParse(myString, myInteger) then
  begin
    writeln('The new value of myInteger is:', myInteger);
  end
  else
  begin
  //In case the conversion does not succeed,
  //the next statement will try to convert the myByte number
  //to a string.
  //The string returned will be converted to an integer value
  //with the Parse function.
