Thanks for the welcome.
It's pretty much just what I asked in my initial post. I need to compare two folders and find out if the content is identical. I've got a BC3 script that does that. Supposedly, it sets the %errorLevel% environment variable when it's done executing and I should be able to capture that and use that value to inform my Perl script of the success or failure of that comparison, but I'm not having a lot of sucess. Thus the questions I listed.
If this doesn't work I can parse the report generated by my BC3 script, but this SEEMED the easier option. Also, the current manual audit process specifies a BC3 comparison so I'd like to honor that. If I need to do it differently though, I think that'd be fine as long as it is accurate.
Also, I think learning how to do this correctly will be really valuable in the long run. Scripts generally tend to do a lot of interacting with the environment they run on so becoming adept at accessing and utilizing those values seems like a smart plan.
Thanks so much for being so willing to jump in and help another coder.
