OK. For now that's the best solution for me, but later I will look at 
putting in a separate file.

Thank you Alex and  Thomas, now I see that a long string is being 
prepared to send to the Perl script or something like that. And I'm 
trying to get my Ruby variable in that string. They syntax in the string 
didn't quite look like Ruby, missing quotes and things.

So EOS presumably means something like End of String and is commonly 
used but has no special meaning to Ruby. Confusing also to me that the 
word in front of <<EOS was "Config" which could be just a descriptive 
name or word with a special meaning.

I think this will get me over the hump of using a file to prepare a 
string to send to some kind of Perl script (it's really an OS X app) to 
make a GUI. At the moment I was trying to recover the return from 
calling the "require." That problem will probably go away if I make it 
class or method.
