David,

Thank for your reply, but I'm puzzled by it. Doesn't the code in my 
previous post make it clear that I'm dealing with instance variables? 
The class instance initiates them, e.g., @log, and I'm trying to get 
that with the run_log.log call. This is NOT an attempt to call a method. 
I very carefully copied (I thought) the pattern I saw in several 
authoritative sources, but it doesn't work for me, which is nuts.

I hope this makes sense.
