Do you want to do something like

if vollabel == "thislabl" then dosomething

I think I can whip up a program to do that. Batch files, though, can
usually only process the errorlevel returned from a program. I'm still
working on setting parent environment variables, so it'll be a week or
more before I can do that. (a simple one could be written after work
tonight)
