I have found that.  Good tool to use.

Also, I am still trying to wrap my head around the line terminating 
error I showed you.  I want to try other scenarios besides conditional 
operators to see what happens.

Lastly, I reduced my assignment statement to two lines:

    %r{(?:([-]?\d+)\s*)??([-]?\d+)(/)(\d+)}xms =~ frac
    w, n, d = $3 ? [$1.to_i, $2.to_i, $4.to_i] : [1, frac.to_i, 0]

... which adds the slash check, rather than using a separate regex. 
Probably still "weird", but that's ok.  :)

I think I need to start a new thread with new material.  20+ entries is 
probably enough.  For now, I'm on chapter nine of "The Ruby Programming 
Language", which is an in-depth tour of Ruby syntax.  Good stuff.
