OK, I see that I stopped at ubygems.rb:10

Question 1:  Why did the debugger stop there and not continue with
statements 3& 4 in my test program?  Is my Ruby installation messed
up?

Q 2: Why do I have a "upygems.rb" in my installation that has nothing
substantive than "require 'rubygems'"?

Q 3. Does the presence of this strangely named file "upygems.rb"
suggest my Ruby installation is messed up?

I continued the processing from the current point as shown below.

Q 4. Since I put a breakpoint at "upygems.rb:3", why didn't the
debugger stop there instead of running through the entire remainder of
the test program?

Thanks again in advance for any insights you may offer.

Regards,
Richard
