RE: [mv] $Safe{scratch} in a UserTag?

******    message to minivend-users from "Eric Frisch" <ericf@conetra.com>     ******

I have not directly accessed [data session arg].  I grep'd the following out
of the source, maybe worth a try:

$Vend::Session->{'arg'}

Anticipating the next question, here are a couple other useful samples:

$::Values->{'mv_searchspec'}
$CGI::values{foo}

It was brutal figuring this stuff out the first time, there are very few
references in the mail archive on accessing and setting these things.  I am
always afraid that I am going to trash some internal data structure and
destabilize MV by doing this, one may want to tread carefully . . .
