- A basic human interface requirement is that all input requested from humans
- be read by characters and never assume that the user will enter data in the
- form requested. Build yourself a library of input parsing routines. As
- your library becomes more robust, requesting input from users and
- responsive error messages will be handled easily and consistently from
- application to application.
