[GEMPAK #QRH-818514]: gempak 5.9.4 dclsfc (synoptic) decoder bug?

Art,

You are correct! I see what you were looking for now. I did make a local change 
back in 2001 to
add the 12 hour max/min values that did not get updated into the NCEP release 
when
the entire directory structure was migrated during the C transition of the grid 
library routines.

I'll add them back and send them on to you!
