The Analytics/Semantics Definitions reports can help with identifying dead code. The Pos_Cnt field is the number of references detected by the tool. So a zero means not used Another way to to identify unused symbols is to look for the symbol in the Analytics/Semantics References report. If a symbol is not shown as referenced in the References report, then the Definitions.Pos_Count should be zero. So, you need to be careful interpreting the results. Some things to be aware of: event-handlers may be needed but not explicitly called, and late calls (CallByName and dynamic) are not counted either. So it is possible to detect 0 calls, but still have calls at runtime. And, this gets more difficult when dealing with a members in COM DLLs. One would need to inspect all client code that might use the DLL to see if the member is called through COM. If you only have EXEs, this complexity is not a concern. The Assessment Report workbook we prepare for a Smart Start includes a Member Counts report that combines the Definitions, References, and _MEMBER_ search report data to compute a usage. The assessment also accounts for multi-component systems and calls through COM. |
