Hi Randy,

Well, DSSERVE will never complain _unless_ you have a syntax error
in your invocation command line.  DSSERVE does not check to see if
the data you are trying to use in a dataset is of the type that you
are saying it is.

Good catch!  That is a glaring omission form the documentation.

And, oops: the DSSERVE command should be:

DSSERVE ADD RJA/NX NEXR TYPE=IMAGE DIRFILE='/d2/nexrad/lwx*.n0r'

Also, you should use the regular expression specified as the value of
DIRFILE with 'ls' to see if you have the correct pattern.  Example:

ls /d2/nexrad/lwx*.n0r

If the 'ls' invocation shows the expected list of files, then the pattern
is correct.  If it does NOT show the expected list of files, then the
pattern is incorrect.

Finally, the files specified in the dataset must be readable by the user
trying to access them.

Really finally, if the IMGLIST RJA/NX ID=<id> still doesn't work, then
you should turn trace debugging on:

IMGLIST RJA/NX ID=<id> TRACE=1

The file 'trce' should be created in your McIDAS working directory if
the dataset is LOCAL-DATA or in the ~mcidas/mcidas/data if the dataset
is served through the remote ADDE server.  Look through the file for
clues as to why the serving is failing.


Cheers,

Tom
