Is the dataset going to be handled by the remote ADDE server, or will
it be a LOCAL-DATA set?  What I am thinking is that the directory into
which these data are to be written is not writable by the user running
the ADDE server.  If the server is the remote one, then this would
be a file permission problem for 'mcadde'; if it is a local one, the
problem would for the user running the McIDAS-X session.

Is anything produced, or is the failure total?  If total, I suspect
a write permission problem.

Robert,

I took the liberty of logging onto your machine and trying a couple of
things:

cd mcidas/data
dsserve.k LIST
redirect.k LIST
imgcopy.k RTIMAGES/EDFLOATER-I RTIMAGES/WXDATA.1
Beginning Image Data transfer, bytes= 310176
Transferring AREA data outbound, bytes= 310256
imgcopy.k: Error writing area directory
imgcopy.k: done

The error on the imgcopy.k is the same as you reported for the IMGREMAP.
The next thing I wanted to verify was whether the RTIMAGES dataset
was going to be handled by the remote ADDE server or by 'weather':

dataloc.k LIST

Group Name                    Server IP Address
--------------------         ----------------------------------------
BLIZZARD                     128.117.140.56
MYDATA                       <LOCAL-DATA>
RTGRIDS                      PSNLDM.NSBF.NASA.GOV
RTIMAGES                     PSNLDM.NSBF.NASA.GOV
RTNIDS                       PSNLDM.NSBF.NASA.GOV
RTNOWRAD                     PSNLDM.NSBF.NASA.GOV
RTPTSRC                      PSNLDM.NSBF.NASA.GOV
RTWXTEXT                     PSNLDM.NSBF.NASA.GOV
TOPO                         PSNLDM.NSBF.NASA.GOV

<LOCAL-DATA> indicates that data will be accessed from the local data directory.
DATALOC -- done

This listing tells us that it will be handled by the remote ADDE server
which is run as the user 'mcadde'. 

If I change the RTIMAGES data server to be LOCAL-DATA, a rerun of the
imgcopy.k above works:

/export/home/weather/mcidas/data% dataloc.k ADD RTIMAGES LOCAL-DATA

Group Name                    Server IP Address
--------------------         ----------------------------------------
RTIMAGES                     <LOCAL-DATA>

<LOCAL-DATA> indicates that data will be accessed from the local data directory.
DATALOC -- done
/export/home/weather/mcidas/data% !imgcopy
imgcopy.k RTIMAGES/EDFLOATER-I RTIMAGES/WXDATA.1
Beginning Image Data transfer, bytes= 310176
Transferring AREA data outbound, bytes= 310256
IMGCOPY: RTIMAGES/EDFLOATER-I.9 copied to RTIMAGES/WXDATA.1
imgcopy.k: done

So, the problem is a lack of write permission for the user 'mcadde' in
the home directory of 'weather'.

Tom,

I guess I was confused about Local-Data.  I understand now,
the machine name of this machine is not the same as Local-Data.

Sorry for the dumb question..
