Mark,

The addendum file is cumulative.  The updates in the file get used if
you use the mcunpack script in the ~mcidas/mcidas7.6/update directory
and then cd to the ~mcidas/mcidas7.6/src directory and do a make all
followed by a make install.all.

The addenda are not announced by email.  They are "announced" on the
McIDAS-X homepage, and users are encouraged to check it from time to
time.

re: I could not get listings of GRID files off of cirrus

When I "point" at cirrus, and try to get a listing of GRID files, here
is what I see:

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 -- done

GRDLIST RTGRIDS/MRF.ALL FORM=FILE
GRDLIST: No Data Found
GRDLIST - done
GRDLIST failed, RC=2

The fact that I can get a listing from DSINFO tells me that the ADDE
remote server is installed and is operational.

The "No Data Found" message from GRDLIST tells me that either there is
no data (i.e., no GRID files) in the dataset RTGRIDS/MRF or that the
ADDE setup is incorrect (the mapping between GRID files and ADDE
data set).  The ADDE setup can be checked from your end by running
the following in a McIDAS-X session:

DSSERVE LIST RTGRIDS

This will tell us the mappings between actual GRID files and the datasets
that are supposed to contain them.  The output from this should look
like:

GRDLIST RTGRIDS/MRF.ALL FORM=FILE
DATASET NAME: RTGRIDS/MRF
 Dataset Position  Creation Date Max Grids         Directory Title
 ----------------  ------------- --------- -------------------------------

When we get the remote ADDE access working to your machine, I can look
through the GRID files in the RTGRIDS/MRF dataset to see if they
look like what I suspect.  After that, I can help you track down
(through a possible reconfiguration of the XCD grid decoder setup files:
RTMODELS.CFG and NOGRIB.CFG)) the reason that you do not have all of the
GRIDs as Bill noted earlier.
