Also, note that PowerShell is a .NET language and its structured exception handling is based on .NET and is fully compatible with it. If no active TRY is found after throwing an exception, then an unhandled exception message is printed to stderr, all processing is terminated within the current CMD shell, and control is The positive values are a good idea because other callers may use the IF ERRORLEVEL 1 syntax to check your script. Jumping to EOF in this way will exit your current script with the return code of 1.

This is probably a good thing, given that error reporting is handled by convention - there are no strict rules. But there are many exceptions to this general rule. What is Wilson's theorem?

Return Code Conventions By convention, command line execution should return zero when execution succeeds and non-zero when execution fails.

The master script was able to successfully catch an exception raised by divide.bat, even though it had to pass through testDivide.bat, which knows nothing about exceptions.

Return Error Code From Batch File

To check if error occured after execution of DOS command or after call of external program use this (tested on Windows XP): IF %ERRORLEVEL% NEQ 0 GOTO ERROR_HANDLER where ERROR_HANDLER is http://steve-jansen.github.io/guides/windows-batch-scripting/part-3-return-codes.html Right now, it looks like any time invested in learning and using PowerShell will be time well spent. Try Catch Batch File Finally I'll write a master script that calls the naive testDivide and properly handles the exception: master.bat @echo off setlocal call exception init %@Try% call testDivide %@EndTry% :@Catch echo %exception.Msg% detected Batch File On Error Goto Development history can be traced at: http://www.dostips.com/forum/viewtopic.php?f=3&t=6497 Below is script to test the capabilities of EXCEPTION.BAT.

I think this method is a valuable tool that may facilitate the management of "errors" in Batch code in a simple and powerful way. In powershell ,I was using below code function a(){ try { ping asdfasdf ping 171.21.000.145 ping ghgsjhsjs Write-Host "success" exit 0 } catch { Write-Host "failure" exit 1 Either way, the stack will preserve all exceptions if rethrow is used. http://introbuilder.net/batch-file/windows-batch-command-error-handling.php It has been used to: Create PrintHere.bat - an emulation of the 'nix here document feature Create a RETURN.BAT utility that any batch "function" can conveniently CALL to return any value

Location = C:\test\testException.bat<:Sub> Rethrowing modified exception Unhandled batch exception: Code = -1 Msg = Main Exception! Capture Error In Batch File This is generally good batch programming practice anyway. 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.

You have to code for halting on error. Please, don't misunderstand me. This blog entry by Batcheero explains perfectly why you should never SET the ERRORLEVEL variable. Each iteration has two CALLs, one to a :label that demonstrates normal exception propagation, and the other to a script that demonstrates exception propagation across script CALLs.
