Abstract
Object-code instruction traces are employed to analyze selected instructions of a year-2000 (Y2K) remediated application program for possible remediation failure when confronted by a year-2000 date. The analysis includes directly identifying one or more instructions of the remediated application program that may fail. A remediation-failure-pattern descriptor is assigned to each examined instruction which is indicative of whether the remediated instruction may fail when confronted by a date in the year-2000 range. The analysis employs user-specifiable run-control values, as well as predetermined filter-specification values in comparing traces of each selected object-code instruction to predefined remediation-failure patterns.
