Art, Not every wmo header that begins with ^P is a redbook graphic, and you are correct, that you won't see a message if no drawing commands are found in the file. I maintain the PIL id's for dcredbook in $GEMTBL/nafos/redbook.tbl if you need to cross reference a pil. The table used by ncep to generate the pil and wmo headers of the products that the centers create using NMAP2/GEMPAK for the data stream are found under $GEMTBL/pgen/awdef.tbl.
