The following trappable error codes may be returned from various operations. If automatic error trapping is enabled (the default situation) then the compiler generates code to automatically check operations for trappable errors and report any errors detected. If you want more control on how errors are handled you can disable error trapping using the built-in procedure TrapErrors, and then use the function GetLastError to check the last trappable error that occured.
