I agree that it is good to see working code but it is not always possible to post it. If, like me, you do the majority of your coding at work you could get in BIG trouble for posting what is effectively someone elses property.
I would like to see code if possible, but isn't the purpose of 'CUFP' to inspire you as to what is possible and spur us all on to greater achievments? - for which the code is not necessary.
