UV release 9/10:

CHECK.SUM file - according to help, derives checksum from first field in @
record (stupid!), or, if no @-record, then check sums the entire record.

Question is, if you *do have* and @ record (as almost all files have) and
*want to check sum the entire record* (as you almost always want to) how to
do it? Adding ID-SUPP does not work.

Thanks, Chandru Murthi

ps Yes I know about the uv group, but I'm sure someone here knows the
answer... thanks.
