Luisa,

The "gdal16" command is just a bat file changing a few environment variables
for the local shell - primary the path.  It does not have any effect beyond
the current shell.

Also, it is affecting which GDAL utilities you pick up at the command line.
It does not affect which version of GDAL is used at runtime by things like
GRASS, MapServer or QGIS.  These are all linked against a particular
version of GDAL - in the case of GRASS 1.5.

So if you want to work with GRIB files I would suggest running "gdal16"
in a shell, and then using gdal_translate to convert the grib file into
a working format like GeoTIFF which you can subsequently use in GRASS.

My hope is that after the GDAL 1.8 release we will make GDAL 1.8 the
default version of GDAL in OSGeo4W and update GRASS and other packages
to use it.  The fact that 1.5 is still the default version in OSGeo4W
is my fault.

Best regards,
