  41 |   Description   :  Moves the form window cursor to the location required
  42 |                    by the form driver to resume form processing. This may
  43 |                    be needed after the application calls a curses library
  44 |                    I/O routine that modifies the cursor position.
  45 |
  46 |   Return Values :  E_OK                      - Success
  47 |                    E_SYSTEM_ERROR            - System error.
  48 |                    E_BAD_ARGUMENT            - Invalid form pointer
  49 |                    E_NOT_POSTED              - Form is not posted
