Thanks Barry. I was hoping to be able to make permanent changes to the
ramdisk file while running pwl/doc. Is there any other way other than to
uncompress the whole ramdisk file to the ramdisk? Ultimately I would
like to make modifications to lilo.conf or any other file in pwl without
having to pull out the DOC and doing it in a reader.

Thanks,
Stephen
