Yeah, thanks for the input Steve. I fully agree with your statement about
to many features dooming a project. If I decide to add any claculations I
will add them last and only after everything else is working. BTW I will
have to have another read of you artical in C=Hacking, It will probably
make more sense to me this time around.
