However, at the set time (4am daily or so), it always does things differently with an error. The syntax couldn't be simpler: ERRORLVL number or SETERLEV number where number can be any number from 0 to 255. SomeFile.exe IF %ERRORLEVEL% EQU 9009 ( ECHO error - SomeFile.exe not found in your PATH ) It’s hard to know this stuff upfront – I generally just use trial and error However, this can be fixed by using the following code to check for non-zero return codes: IF %ERRORLEVEL% NEQ 0 ...

As far as basic error checking goes, it is always wise to check for the existence of essential files before working with them – a simple “if exist” condition can control http://www.robvanderwoude.com/battech_debugging.php The positive values are a good idea because other callers may use the IF ERRORLEVEL 1 syntax to check your script.

One last useful tip is to output or log the “last error” as the last action, using the ERRORLEVEL variable within the batch file – 0 is generally used to indicate Uh oh, something bad happened exit /b 1 ) Or to give more info about what happened c:\mypath\myexe.exe 2&1> myexe.log find "Invalid File" "myexe.log" >nul2>nul && echo.Invalid File error in Myexe.exe Thanks for your help. @echo off setlocal set _source=C:test7zipbak set _dest=C:test7zipbak set _wrpath=C:Program Files7-Zip if NOT EXIST %_dest% md %_dest% for %%I in (%_source%*.txt,%_source%*.cpi) do "%_wrpath%7z" a "%_dest%%%~nI.7z" "%%I" & del weblink A certain errorlevel may mean anything the programmer wanted it to.
