in reply to 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"; }
      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 = $color\n"; }
    • if (($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.
