25 *  This directive will invoke the fatal error handler supplied by the user
26 *  followed by the the default one provided by the executive.  The default
27 *  error handler assumes no hardware is present to help inform the user
28 *  of the problem.  Halt stores the error code in a known register,
29 *  disables interrupts, and halts the CPU.  If the CPU does not have a
30 *  halt instruction, it will loop to itself.
31 *
32 *  Input parameters:
33 *    the_error - fatal error status code
34 *
35 *  Output parameters:
36 *    the_error       - on stack
37 *    status register - on stack
38 *
39 *  NOTE: The the_error is not necessarily a directive status code.
