Anomalous Script behavior

I've run into situations like this and it usually seems to be caused by an
unexpected value in a variable passed to an lc function or command which
causes it to silently quit and stop the rest of the calling script from
executing.  Hard to define what "unexpected" means and I'm trying to think
of an example but it's been a while since it happened to me.

I would add some code to your tracking mechanism to track the value of any
critical variables, especially those that are passed as parameters to other
