I've never been able to find documentation on how to write pre/post commands; is there one available? Specifically, I'm throwing an error (exit /b 101) in a Pre- command, ATIW Echo (9.7.8206) reports the error in the log, then continues anyway! (Yes, I have the option "Abort the operation if the user command fails" checked.) Is there some specific way ATI requires errors from Pre/Post commands to be communicated so it can actually do what the option "Abort the operation if the user command fails" says? And, is that documented somewhere?
