canDefault                                       (Assignable)

        Contains a logical value indicating whether the subsystem can perform
        default error recovery for the error condition.  A value of true
        (.T.) indicates that default recovery is available.  Availability of
        default handling and the actual default recovery strategy depends on
        the subsystem and the error condition.  The minimum action is simply
        to ignore the error condition.

        Default recovery is requested by returning false (.F.) from the error
        block invoked to handle the error.  Note that Error:canDefault is
        never true (.T.) if Error:canSubstitute is true (.T.).
