(i think) the reason you always get OK, is because the if c.scan always 
returns a true value (the scan method always takes place) (i.e, it never 
returns nil/false)...i don't know exactly what method you need, but 
first of all check out 
http://rubycentral.com/book/ref_c_string.html#String.scan to see that it 
returns either an array or a string, and second of all maybe, check out, 
Regexp#=~ , maybe that is better?
