Subject: Re: Problem with sort!

The real function was a little more complex than
could be done by sort by. I tried to generate
a smaller example, and confused myself.

I refactored a little to reduce duplicating
code - basically I have 2 separate sort methods,
depending on a value in the data - but they're
substantially the same.  Anyway, by putting
the common code in a method and having sort
do something like vals.sort!{|a,b| sortfunc(a,b,sortflag) }
things seem to work.

Thanks to the list for all the help.

Hopefully my next problem/puzzle will be more
interesting.
