Sorry, I missed the my $operacion; declaration. Still I would advise you to use -text instead of -textvariable since you are not capturing the references to the variables anyway.

Update: Another thing I would do is to make sure each line has the right format before processing it: 

foreach my $stat1(@stat1)
{
    chomp ($stat1);
    my $operacion;
    my $stado1;
    ($operacion,$stado1)=split(/\|/,$stat1);
    next unless defined($stado1);
    ...
}

The next statement will skip blank lines and lines that do not contain a |-delimiter.
