create a non-fatal error.
(The executed FAL number 001 to 511 will be stored
in A360 to A391. The number 4 will be added to the
front of 101 to 2FF (which correspond to executed
FAL numbers 001 to 511) and the result will be
stored in A400 as error code 4101 to 42FF. )
Check the conditions for executing FAL instructions and
