OK, thanks for the information. I have a better understanding of what you are
trying to accomplish now.

I assume that "They" means the folks at the SSEC Data Center...

OK, looks good so far.

One thing you have to be aware of is that by defining a dataset to include
all images in AREA format, you run the risk of accessing/overwriting a file that
already exists.  The Unidata McIDAS distribution comes with several files in
the 9000 block of AREA file numbers.  Here is a listing that shows this:

% dmap.k AREA9

You do not want to overwrite these files.

re:

> IMGCOPY: done

Here, you should be very specific of the dataset position of the 
file being created so you do not overwrite an existing file.  I
suggest the following invocation:

IMGCOPY OGOES12/SNDR STORM/SOUNDER.3000 BAND=ALL

This will create the file AREA3000 in the first writable directory
contained in set of directories represented by the environment
variable MCPATH.

re:

Since your IMGCOPY invocation said that you wrote to STORM/SOUNDER.9996,
the file AREA9996 should have been created, AND it should have been 
created in the first writable directory in your MCPATH.  You can 
check this by running:

DMAP AREA9996

What is the value of MCPATH?  Get this by running the following from the
Unix/Linux command prompt:

echo $MCPATH

Since you indicated that you are running from your own login, your MCPATH
should look like:

/home/boris/mcidas/data:/home/mcidas/data:/home/mcidas/help

If your MCPATH is different from this, your account has not been correctly
setup to use Unidata McIDAS.

re:

Check the definition of MCPATH first.

Once an output file has been created by IMGCOPY, you should be able to diectly 
access
it from McIDAS-V if McIDAS-V is running on the same machine.  In this case,
you could use:

Data Explorer -> Data Sources -> General -> Files/Directories

You can also have McIDAS-V setup an ADDE dataset from the file(s) you have
created with IMGCOPYs.

If you are running McIDAS-V on a different machine, you should consider
setting up the remote ADDE server on the machine on which you are running
McIDAS-X.  I can help you do this.

re:
> or data belonging to
> the groupOGOES12/SNDR can be displayed and manipulated directly from McIDAS V?

It could, but it is likely that you will want to access the image multiple 
times,
and repeated access may force the SSEC Data Center folks to charge you for
the access.  I think it is better to copy the images you want from the server
to your local machine once, and then access them as many times as you like.

No worries.  One of my jobs is to help users learn how to make use of the tools
we provide :-)

If you continue to have problems, I would be happy to logon your machine and
setup things so you can be productive.

Cheers,

Tom
