Wow, thanks for the quick replies! I hadn't realised that & was purely a bitwise operator. In the strongly-typed Java world, & works as a non-lazy (exhaustive?) boolean operator so it has to return a boolean for boolean inputs. Thats the difference here, and Robert got it in one. Gavin. PS. A code restructure isn't really appropriate here. The original executes several SQL statements inside a transaction and needs to know whether to commit or rollback at the end. The example was simplified to get the point across but thanks for the suggestions.
