Richard,
The unitalized warnings are probably coming from one or more of $fgh, $ijk,
$lmk being undefined because the regex failed to match anything. You can test
this by trying to print the values of these variables.
They are probably undefinately because the record seperator is being set
lexically inside of the loop (and thus won't apply to the outer while). Please
consider this code:
local $/ = "\n\n";
while (<FH>) {
++$count;
my $fgh =~ /fgh\s+(\S+)/;
my $ijk =~ /ijk\s+(\S+)/;
my $lmk =~ /lmk\s+(\S+)/;
no warnings qw(uninitialized);
warn "1: $fgh, 2: $ijk, 3: $lmk\n";
push @yahoo, join('_', $fgh, $ijk, $lmk);
use warnings;
}
Cheers,
-J
