Re: Comma Delimitted Fields..

split the color field ($data[1]) into an array and the print the colors like so:

#!/usr/bin/perl-Tw
use strict;

use Text::ParseWords;
open(DATA,"basicdez.dat") || die "Cannot open datfile: $!\n";
my @data;
my $i = 0;

while (<DATA>)
{
  chomp;
  last if /^"EOS"$/;
  {
  @data = &quotewords('\s+', 0, $_);
  }
      # if all fields exist (gets rid of PER issue)
   if (($data[0]) && ($data[1]) && ($data[2])) {
      my @colors=split(/,/, $data[1]);
      print "Name   = $data[0]\n";
      for (@colors){
         # print each color
         print "Color  = $_\n";
      }
      print "Date   = $data[2]\n";
   }
}

Two small remarks: `for (@colors){ print "Color = $_\n"; }` [download] can lead to nasty surprises as you are overwriting $_ of the while loop. So either add `local $_;` before the loop or use a loop variable `for my $color (@colors){ print "Color = $color\n"; }` [download] `if (($data[0]) && ($data[1]) && ($data[2])) {` is quite restrictive. This doesn't allow for empty fields or lines without date. Alternatives would be `if (@data == 3)` or the `next if` suggestion by dragonchild. Of course, basicdez has to specify himself which of the alternatives fits his requirements. -- Hofmator	[reply] [d/l] [select]
