ok, so split by more than just escaped pipe. pad both sides with a
single space. if tabs have crept in your source first sub-out out
occurrences of tab by $ThisVar =~ s/\t/ /g; # if particularly dirty,
use up to three of these.
also, if you're new to Perl, keep the syntax simple, so maybe use the
$ThisHashTallyForIP{$ThisIP}++ ; # for when you're going over the
file, array, hash, or SQL read-in you're doing.
