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 in the "past". The positive values are a good idea because other callers may use the IF ERRORLEVEL 1 syntax to check your script. In DOS for the rest of us, we can use FOR loops to determine the errorlevel: @ECHO OFF REM Reset variables FOR %%A IN (1 10 100) DO SET ERR%%A= REM http://sammcallister.com/batch-file/display-errors-in-a-batch-file.html

One simple way to verify if your batch file should work as a scheduled task is to call it from an existing cmd.exe process from a different current working directory (such http://steve-jansen.github.io/guides/windows-batch-scripting/part-3-return-codes.html Complete example: copy N files from location A to the B and after each step check for error, if error occured print 'Error' otherwise 'Sucess'.

To execute a follow-on command after sucess, we use the && operator: SomeCommand.exe && ECHO SomeCommand.exe succeeded! But there are many exceptions to this general rule.
