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
