19990708: garp continued

Lynn,

You can use gddelt to remove the offending grids and this will
make garp happy. Use gdnum=list to list out the grids and
remove by numbers.

You should be able to use gdmod to copy all the eta grids to a single file.
You can use gdcfil to create the empty grid file using cpyfil=#104 (or one 
of the existing files).
