Excellent. Glad to hear it.

I am willing to bet that your XCD grid decoding is not up to the latest
addendum. At some point in the not so recent past, an addendum was
made to McIDAS-XCD 7.6x that covered splitting up decoding of MRF grids
into MRFs and AVNs. Assuming that you are still running your ADDE
server on cirrus, I see that this change has not been made:
DATALOC ADD RTGRIDS CIRRUS.LSC.VSC.EDU
Group Name Server IP Address
-------------------- ----------------------------------------
RTGRIDS CIRRUS.LSC.VSC.EDU
<LOCAL-DATA> indicates that data will be accessed from the local data directory.
DATALOC -- done
DSINFO G RTGRIDS
Dataset Names of Type: GRID in Group: RTGRIDS
Name NumPos Content
------------ ------ --------------------------------------
ALL 400 Real-Time Grids
ECMWF 10 ECMWF Grids
ETA 40 ETA Grids
JET 10 LSC Jet Stream Grids
MISC 10 Miscellaneous Grids
MRF 100 MRF Grids
MRF-UW 2 MRF Grids in UW stream
NGM 40 NGM Grids
NGM-UW 2 NGM Grids in UW stream
RUC 80 RUC Grids

Compare this to the same DSINFO listing from adde.unidata.ucar.edu;
DSINFO G RTGRIDS
Dataset Names of Type: GRID in Group: RTGRIDS

ALL 1000 All XCD Real-Time Grids

ECMWF 10 Real-Time ECMWF Grids
ETA 120 Real-Time ETA Grids
GRIDS 9999 All Possible GRID files
MDR 10 Manually Digitized Radar
MISC 10 Real-Time Miscellaneous Grids
MRF 100 Real-Time MRF Grids
MRF-UW 2 MRF Grids in UW stream
NGM 40 Real-Time NGM Grids
NGM-UW 2 NGM Grids in UW stream
RUC 80 RUC (MAPS) Grids
DSINFO -- done
I could not get listings of GRID files off of cirrus, so I am suspicious
that the ADDE server for this data, at least, has changed at Lyndon.
If you could point me to the correct server machine, I could take a
closer look.

Tom,
Thanks for the quick reply.
Mark is checking out the latest addendii and should respond
to you further. I will look in next week and see what is
happening.
I could probably test my scripts on the correct data stream
by pointing at your server. They used to work, but the world
keeps changing.
I think I have almost all commands upgraded. There are still
a few IGG MAKE 's, and IGU DEL then IGU MAK. I don't see
that these are being sunset soon. Should I leave them or
change them too?
Bill
