Breo, I looked at the NCEP and the WMO documentation and I didn't see any reference to using 9th integer bit 7. Also, what octet is the 9th integer? I'm assuming it's the resolution and component flag that uses code table 7, that states bits 6-8 are reserved. Can you point me to the documentation? Robb....
