This corresponds to my installation of McIDAS-X v2003. >Messing around a bit, I try: >GRDLIST RTGRIDS/GFS DAY=03248 TIME=0 LEV=500 PARAM=Z NUM=ALL >and I can see them all the way out to 240 hours including 144 hours I just verifie dthis. >BUT >GRDLIST RTGRIDS/GFS DAY=03248 TIME=0 FHOUR=144 LEV=500 PARAM=Z >GRDLIST: No grid found matching search conditions >Perhaps I missed an announcement about how these things are filed? No. I think you are the second person to uncover a bug related to processing of an FHOUR= value being greater than 128. This sounds like a requested time is being stored in a char variable in the server somewhere. A char is a signed 8-bit quantity, so values greater than 128 will be treated as negative numbers. Access to the same GRID field through grid number works with no problems: GRDLIST RTGRIDS/GFS DAY=03248 TIME=0 LEV=500 PARAM=Z NUM=ALL ...

I will let you know when I have found the problem and implemented a fix. >Bill >Dr, William T. Corcoran >Geography - SMSU >901 S.
