Re: Array comparison returning nil

Could it be that some of the elements in your arrays cannot be compared,
like "a" and 1 ?

You can help this by mapping all these elements to numbers or strings, which
can be sorted,
as in this example

a = ["three",3, "four",4]
c = ["ten",10,"eleven",11]
b=a.sort{ |x,y| x.to_s <=> y.to_s}<=>c.sort { |x,y| x.to_s <=> y.to_s}
puts "result is #{b}"

which gives a result -1, since 3 is smaller than 10.

Best regards,

Axel

Unfortunately, all I remember is that it sucked.

*LOL* I never thought I'd see the day when 5 million people were called a
"small special interest group"!

Unfortunately, network execs are like the fox coveting grapes it can't
reach. If they think they can substitute a 6 million audience for the 5
million they'll try it. They are driven by the illusion that someday it
will be possible to have all of the audience all of the time.

It's always amused me that business execs seem to forget that the goal is to
make a profit. Period. It's not to make all the profit that can possibly
be made, because that's a zero end game - once you do it, everyone else is
broke, and you can no longer make a profit at all.
