Section 4 of the symptom record contains the secondary symptoms associated with the error incident, and it is provided by the application that incurred the error, or some program that acts in its behalf. The internal format of the data in section 4 is the SDB format, with a single blank separating each entry. Once this data has been passed to SYMREC by the invoker, it may not be added to or modified without setting ADSRSMOD to 1.
