Hi Phillip,

Thanks for you response, which essentially solved my problem. I
published a new version, with a copy of printed output appended, at
http://www.pastie.org/1617782

After following your suggestion and getting different failure, I
finally realized:  Hey, that's just regular ERB code. Therefore,  that
"*" out there would lead to:
    string * string * string
which violates Ruby syntax.  So I got rid of the "*" and got decent
(but not perfect results):  Too many blank lines are generated.

I eliminated one of the blanks by appending a closing hyphen at line
24.  But I couldn't plug the major generated, I believe, by line 26.
Cf. output lines 70-72, 74,76,78 in the Pastie.  If you have have any
insight into that problem,  I'd appreciate one more insight from you.

Best wishes,
Richard
