Re^2: lack an adequate understanding of (at least) the seek function

jeffa,

This is REAL quick (and I am quite a beginner with OO Perl).

I am wondering if the "complaint" I got for my code (which gave me the desired results) is benign.

Here's the code:

#!/usr/bin/perl -w
use strict;
use warnings;
use Tie::File;

my $MAXSAVE = 5;

my $name = "Duane Wade";
my $subject = "My Career";
my $message = "No one ever thought I'd be this good.";

my $myTieObject = tie my @messagesIn, 'Tie::File', 'messageTest2.txt' 
+or die "can't open\n";
$myTieObject->flock;
unshift @messagesIn, "$name|$subject|$message";

if (@messagesIn > $MAXSAVE) 
{
    @messagesIn = @messagesIn[0 .. $MAXSAVE - 1];
}

untie @messagesIn;

1;
[download]

And here's the complaint:

untie attempted while 1 inner references still exist at ./messageTest2.pl line 21 <FH> line 16.

Line 21 is the untie line and Line 16 is the if statement.

Other than that, I am all set and much obliged!

Tony

You are quite welcome o2bwise. The problem is that you are `untie`'ing the wrong thingy. Try this instead: `untie $myTieObject;` [download] And there is no need to have `1;` as the last line of a script. That's only necessary for modules.

Thanks, jeffa. I guess I was fooled by the tie being applied to the array coupled by the following in: http://search.cpan.org/~mjd/Tie-File-0.96/lib/Tie/File.pm#flock "The best way to unlock a file is to discard the object and untie the array." Man, I want to become a solid perl programmer. I was an engineer for several years in semiconductors and have been in software for ~6 years. I scripted (read: SCRIPTED) in perl for five of those. Say, I listened to the song you have posted. Not bad, but the title is much better, i.e. "the triplet paradiddle with a high-hat" - how can you beat that? If you like it, perhaps you might give a song called Serengetti (Grateful Dead off Shakedown Street) a try. All percussion where it gradually adds more and then removes it. Well, thanks again, jeffa... Cheers! o2	[reply]
