Hi Bert,

Thanks for the reply.

The use case I presented involves working code, not diagnosing a script 
in development.

The concern is running a script where something changes outside of the 
script, as I stated. An example of a change is a data source changing 
perhaps the columns in the data source, or even changing the spelling of 
a column. The point is something changes.

The question then becomes how to be aware of the change when the reset 
of the script runs fine, as I presented.

Think of having a script running daily where you are not running it 
manually. How do you know there are errors in the script processing at 
this point?

Does this question now make more sense?
