Tom,

OK, sounds good.

Sounds like there is a problem either in the SCHEMA that is being used
by the XCD decoder, or there is a problem with the decoder itself.  Don
and I just chatted about this and had no ready explanation.  I would suggest
the following, however:

o stop the LDM
o delete today's surface MDXX file
o delete today's .XCD file (spool file containing all of the textual data
  for a single day)
o restart the LDM (and hence the MDXX decoders

Please let me know the results of the actions above.

Me too!  I have been waiting for SSEC to finish several ADDE routines so
I can migrate the GUI to full ADDE use.  At this point a user will be
able to look at data from not only their own site, but also from any
of a number of cooperating ADDE sites around the country.  Look for
an upcoming announcement where I will canvas my ADDE sites and ask for
their permission to add their site into a list of ADDE data providers.
