You can redirect a program's stdout or stderr streams to a temporary file and check that for errors. This return code tells me that both errors were raised. Most programs rarely document every possible return code, so I’d rather explicity check for non-zero with the NEQ 0 style than assuming return codes will be 1 or greater on error. http://stackoverflow.com/questions/6498460/batch-programming-error-handling-and-start-command Identify a short story about post-apocalyptic household robots What is mathematical logic?

Now I can also add exception handling to the list :-) The technique relies on a batch utility called EXCEPTION.BAT to define environment variable "macros" that are used to specify TRY/CATCH A TRY/CATCH block is structured as follows: %@Try% REM any normal code goes here %@EndTry% :@Catch REM exception handling code goes here :@EndCatch - Every TRY must have an associated CATCH. echo *error* ERRORLEVEL is now: %ERRORLEVEL% echo.
