Hi,,

I putting together examples I might use in teaching an elementary Ruby
seminar.  for the moment, I like to code examples inside a method that
displays both the code and the result of the code's execution.

I pasted both the code and the output presented by running the code
under SciTE at http://www.pastie.org/561156.

My problem is the spurious final line of output from the show method:
"1256921" from Example 4.  I like to learn why that's generated so
that I can eliminate it.  I repeated the Example 4 code out of the
"show" context,  and it executed as I expected, i.e. no "1256921" ws
generated.

Any ideas?

Thanks in Advance,
Richard
