John,
Can you explain a little better how this is working in this situation,
though? His data looks like
1311001
Aed Motorsports
5373 W 86th St
Indianapolis, Indiana 46268 U.S.A.
7069210
Bird Electronic
30303 Aurora Rd
Solon, Ohio 44139 U.S.A.
1020700
Charis Disk Golf
Ste 160-13
4000 W 106th St
Carmel, Indiana 46032 U.S.A.
Or at least that's how it came across in my email. In that case I
don't see how $/=''; is producing the output he describes, unless
there's something strange going on with line endings.
Or is this just some strange line wrapping arifact gmail is inflicting on me?
Thanks,
