I'm going through a script trying to make it work with -w. I'm getting a lot of "Use of uninitialized value" errors, but I can't seem to tell how to fix it.
For example, I get the message "Use of uninitialized value in concatenation (.) at mtparse.pl line xxx, <DATA> l ine 1."
The corresponding code looks like:
sub readPorts(\%) {
 die "Incorrect number of args to readPorts\n" unless @_ == 1;
 my $portHash = shift;
 
  while (<DATA>) {
  my ($port, $sname, $rem) = split("\t");
  push (@{$portHash->{$port}},$sname . "\t" . $rem);
 }
}

[download]
The line indicated by the warning is the push(...) statement. I've tried giving explcit values to $port, $name, and $rem before the split to no luck. I also tried giving values to @{$portHash->{$port}}, and $portHash->{$port} and I get the same warning.
What am I not initializing, and how should I do it? I feel like I'm missing something simple here, but it's beginning to feel like I can't see the forest for the trees.
