@anthony: It might even be the 4th time I posted it. I went back to each of the places where I had almost but not quite found information about the problem I was having and updated each of those. The web should have a few different ways to discover the problem I encountered and describe ways to fix it. Correcting the misconceptions I had is just part of the process.
Posting it here was useful as @mjh563 was able to associate the symptom that I saw with additional relevant details.
I removed the "@require" line from my script.
thanks, Chuck
