LEARN_BEGIN and LEARN_END

  These built-ins save all keystrokes typed between LEARN_BEGIN and
  LEARN_END.  LEARN_BEGIN starts saving all keystrokes that you type, until
  LEARN_END is used.  LEARN_END stops the "learn mode" and returns a
  sequence comprising all the keystrokes you entered.

  Syntax

     LEARN_BEGIN ({EXACT | NOEXACT})
               .
               .
           [your keystrokes]
               .
               .
     learn := LEARN_END;

  Parameters

     EXACT      Specifies that input entered for each READ_CHAR, READ_KEY,
                or READ_LINE is read as the input for these built-ins when
                the learn sequence is replayed.

     NOEXACT    Specifies that DECTPU should prompt for new input each time
                a READ_CHAR, READ_KEY, or READ_LINE is replayed within the
                learn sequence.
