Hi Athanasius, The main reason behind my initial posting was that, when I used regular expression to parse the CSV file with one or more lines as shown in the code below, it always worked fine. I couldn't figure out why the print outside the while loop didn't work when using the Text::ParseWords quotewords. 

$file = $ARGV[0] or die "Missing CSV file on the command line\n";
open($text, '<:encoding(UTF-8)', $file) or die "Could not open '$file'
+ $!\n";

@fields = ();   # initialize @fields to be empty

while ($line = <$text>)
{
    chomp($line);    # remove the newline at the end of the line
    while ($line =~ m/"([^"\\]*(\\.[^"\\]*)*)",?|([^,]+),?|,/g) {
        push(@fields, defined($1) ? $1 : $3);    # add the matched fie
+ld
    }
    # push(@fields, undef) if $line =~ m/,?/;    # account for an empt
+y last field
}
foreach $field(0..$#fields)
{
    print $field + 1 . " $fields[$field]\n";
}
close $file;

I am a newcomer to Perl and I am really enjoying it. Thanks for your help.
