Hi

We now have

#!d:\perl.5.8.8\bin\perl

use CGI qw(:standard);
use CGI::Carp qw(fatalsToBrowser);
$q = new CGI;                        # create new CGI object
print $q->header, $q->start_html("File Size");
print $q->start_form;
print h1("File Size");

my $filename =
"D:\\perl.5.8.8\\site\\lib\\auto\\Sybase\\CTlib\\CTLIB.dll";
my $fh;                    # file handle
open $fh, '<', $filename
      or die "cannot open $filename for reading: $!";

$Size = -s $fh;
print p("Size of $filename = $Size bytes");

print $q->end_form,$q->hr();
print $q->end_html;

which gives us 

File Size
Size of D:\perl.5.8.8\site\lib\auto\Sybase\CTlib\CTLIB.dll = 127057
bytes

So we can obviously read the file ok
The open call from the earlier script was reading the contents of the
list box from file and that all seemed ok 

I think it must be something to do with the path of some env variable.

Your attached test script is very complicated - it does all sorts of
stuff apart from opening a file.  Couldn't you make a simple script that
just does that?

However, it looks like the open() call is not correct - you have

    open(INTERFACES)

which will open a file called 'interfaces', and not give any error if it
fails!  You would need something like

    my $filename = 'whatever';
    my $fh;                    # file handle
    open $fh, '<', $filename
      or die "cannot open $filename for reading: $!";

I think you need to make a test program as I suggested, and if you don't
know how to do that, find a local perl programmer who does.
