Recovering From Unexpected Program Interruption 

A robust application design that uses the Hi-Li intrinsics will include a
REFRESH function key for every form.  The application would implement a
REFRESH function key by calling the HPDSEND intrinsic and passing the
$REFRESH form name token when a REFRESH key request is detected.  With a
design that includes a REFRESH function key, the following recovery
procedures should be used when an unexpected program interruption occurs.

If the interruption occurs because the BREAK key was pressed or because
of a terminal power failure, control returns to MPE. To recover from this
situation, take the following steps:

   1.  Do a hard reset by pressing the SHIFT, CONTROL, and RESET keys
       simultaneously.  Then, press [Return] to display the colon prompt.

   2.  If echo is turned off, press the [ESC] key, then the colon (:)
       key to restore echo.

   3.  Type RESUME. The message READ PENDING is displayed.

   4.  Press the [REFRESH] key to return to the menu at which you were
       interrupted.
