The same way you created them before using strict:
my @array = AN_EXPRESSION_THAT_YIELDS_A_LIST;
Also, while loops are a bad way to process arrays, the for loop is
much more natural:
for my $element_of_array (@array) {
}
If this is the same code as before, you really shouldn't be using
arrays like that. Files should be read using
while (my $line = <$fh>) {
}
not
my @array = <$fh>;
my $i;
while ($i < @array) {
my $line = $array[$i++];
}
