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.
