Hi Todd,

Here is another heads up for XCD:  sigco.pgm does an include of
m0xcd.inc before it does an 'implicit none'.  Since m0xcd.inc declares
types of variables, it will cause a compilation error on some platforms
when built with gcc/g77.  The solution is simple: move the include to
after the 'implicit none'.

On a related topic...  What is _really_ needed in XCD is:

- being able to name output files in a non-standard manner.  Here are
  two examples:

  20040611_sfc.md     - instead of MDXX0003
  20040611_gfs_12.gid - instead of GRIDnnnn

  This is doable now that DSSERVE can create MD and GRID datasets using
  DIRFILE=.  The beauty of this is that it would get rid of the
  incredibly hard to understand RTMODELS.CFG file.

- the ability of XCD to decode GRIB2 model data (this is a biggie!)

- data compression in decoded GRID files

Anybody thinking about things like this?  :-)

Cheers,

Tom
