To specify exception processing behavior
• Using the command line, enter:
Debugger Option General Exceptions
Select Normal, Report, or Stop; then, press the < Return> key.
Normal
The debugger handles exceptions as would the processor.
(default)
Report
The debugger reports exceptions to the Journal window and
then handles them as would the processor.
Stop
The debugger reports exceptions to the Journal window and
then halts program execution.
The Debugger Option General Exceptions command sets the value of @exc.
You can set @exc as you would any program variable. The following table lists
what the values of @exc mean:
@exc value
stop

bus error and address error exception handling is not simulated. Bus errors
cannot occur during simulation, and an address error will terminate processing
regardless of the value of the @exc pseudoregister.
Due to the fact that bus error and coprocessor simulation is not provided, the
only possible exception stack frame formats are $0 (short format), $1
(throwaway), and $2 (instruction exception).
