 *
 *  This directive will invoke the fatal error handler supplied by the user
 *  followed by the the default one provided by the executive.  The default
 *  error handler assumes no hardware is present to help inform the user
 *  of the problem.  Halt stores the error code in a known register,
 *  disables interrupts, and halts the CPU.  If the CPU does not have a
 *  halt instruction, it will loop to itself.
 *
 *  Input parameters:
 *    the_error - fatal error status code
 *
 *  Output parameters:
 *    the_error       - on stack
 *    status register - on stack
 *
 *  NOTE: The the_error is not necessarily a directive status code.
