Bob and the group,

UI-View32 uses a text file that the weather programs format as Andy 
says, in Weather-Display, the WXNOW.TXT file that UI-View32 uses is 
format as:

200/001g024t031r000p000P000b10105h67

And we can see that b10105 is 5 digits which is according to Specs.. 
Maybe some other weather programs are not following the specs for one 
reason or the other?

Robbie
