Re: st: RE: Getting at value labels
I sent a few messages directly to you that you have not replied to; perhaps
your ISP is blocking my address for some reason, thus I'm using this public
forum to try to reach you (everyone else, please forgive me, this will be
the only one). Drop me a note if you receive this and I'll attempt to mail
to you directly... if that fails, I'll try via my Yahoo address.
