Hi,

I'm a newbie to Perl (and convert) but have a curious problem.

I'm using Tie::File in a Windows environment and have got it working just fine in a test project using this:

    tie @file, 'Tie::File', $filepath;
    for (@file) {
        print "$_\n";
    }
    print "line2 = $file[1]";
[download]

This list the file contents and pulls out line 2 as expected. However, when I run the same code within an existing project I'm working on I get the following error:

Empty record separator not supported by Tie::File ...

The file is the same, the code is the same so it's obviously something to do with my project. Trouble is I haven't got the faintest idea what. I tried using

recsep => "\r\n"
[download]

and whilst that read the file, the entire contents were put in $file[0] making it unusable

Anyone have ideas how I can resolve this? Thanks!

Update

A bit more code below. If I run the code snippet mentioned within a sub on the module I receive the error mentioned. However, if I run it outside of the sub the code works as expected. This seems a little strange to me.

package CodeSet;
use strict;
use warnings;
use Tie::File;
use Exporter;
use vars qw($VERSION @ISA @EXPORT @EXPORT_OK %EXPORT_TAGS);

$VERSION     = 1.00;
@ISA         = qw(Exporter recControlObject);
@EXPORT      = ();
@EXPORT_OK   = qw();
%EXPORT_TAGS = ( 'all' => [ qw() ] );

#constructor
sub new {    
    my $class = shift;              
    my $self = {        
        
        };
                
    bless ($self, $class);             
    return $self;
}              

print "outside sub\n";
my $filepath = 'C:/TEMP/test extended code/test1.txt';
my @file;
tie @file, 'Tie::File', $filepath;
for (@file) {
    print "$_\n";
}
print "line2 = $file[1]\n";  

sub Process {
    my $self = shift;
    
    print "inside sub\n";
    my $filepath = 'C:/TEMP/test extended code/test1.txt';
    my @file;
    tie @file, 'Tie::File', $filepath;
    for (@file) {
        print "$_\n";
    }
    print "line2 = $file[1]\n";  
}
1;

In the snippet above, Process is called from another module like this

sub RunCodeSets {
    my $self = shift;
    
    for ($self->CodeSets) {
        $_->Process;
    }
}
[download]

Running it gives me this output

Empty record separator not supported by Tie::File at C:/Documents and Settings/hardyr/My Documents/Development/Versioned projects/Perl/recControlMaker/LocalObjects/CodeSet.pm line 40

outside sub

line 1

line 2

line 3

line2 = line 2

inside sub
