Contact Failed Mail Donate Errorlevels The correct name for errorlevels would be return codes. But since the DOS command to determine the return code is IF ERRORLEVEL, most people use the name errorlevel. Errorlevels are not a standard feature of every command. A certain errorlevel may mean anything the programmer wanted it to. Most programmers agree that an errorlevel 0 means the command executed successfully, and an errorlevel 1 or higher usually spells trouble. But there are many exceptions to this general rule. IF ERRORLEVEL construction has one strange feature, that can be used to our advantage: it returns TRUE if the return code was equal to or higher than the specified errorlevel. This means most of the time we only need to check IF ERRORLEVEL 1 ... and this will return TRUE for every non-zero return code. In Windows NT4/2000/XP this may sometimes fail, since some executables return negative numbers for errorlevels! However, this can be fixed by using the following code to check for non-zero return codes: IF %ERRORLEVEL% NEQ 0 ... Use the code above wherever you would have used IF ERRORLEVEL 1

The customer runs the program from a scheduled task. When the program is run with dos error a certain parameter, the program runs as an interface engine, creating a file and then ftp'ing the file to another server for import by another program. I was wondering if I might have the scheduled task instead run a batch file. The batch file would run the program and check errorlevel as the program exits. If errorlevel is not equal to zero, then batch file would run the program again. Does anyone see problem with my plan to use errorlevel in a batch file? dos error level Here's an example of the batch file: :start myPgm.exe intfc if errorlevel <> 0 then start batch-file share|improve this question edited Mar 21 at 10:42 BartoszKP 22.3k84067 asked Oct 31 '12 at 3:01 user1787319 23113 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted I would write it like so: :start myPgm.exe intfc IF %errorlevel% NEQ 0 GOTO :error GOTO :end :error echo There was an error.

You need either if %errorlevel% neq 0 ... or if errorlevel 1 .... The last form assumes the errorlevel is never negative. Your code is neither and raises a syntax error. –dbenham Feb 28 '14 at 23:09 ok, I understand. –djangofan Mar 1 '14 at 1:53 add a comment| up vote 3 down vote Your IF statement is wrong. It should read if %errorlevel% neq 0 goto start Or your script could read :start myPgm.exe intfc || goto start share|improve this answer answered Oct 31 '12 at 3:45 dbenham 77.9k11114179 Thanks for that feedback.
