  63        These routines insert the character <EM>ch</EM> before the character  under  the
  64        cursor.   All characters to the right of the cursor are moved one space
  65        to the right, with the possibility of the rightmost  character  on  the
  66        line  being  lost.   The insertion operation does not change the cursor
  67        position.

  74        tions.
