Another way would be to use the conditional operator inside a loop

# field number for sizes SM MD LG XL
my @fno =(9,12,15,18);
while (<DATA>) {  ## file2
  my @data = split(',',$_);
  my $ky = $data[0];
  if (exists $stock{$ky}) {

    # check each size
    for my $sz (0..3){
      $data[$fno[$sz]] = ( $stock{$ky}[$sz] eq '0' ) ? '' : '0' ;
    }

  }
  print (join(',', @data));
}

If you substitute $sz with 0 the expression becomes `$data[$fno[0]]` and because `$fno[0] = 9` this equates to `$data[9]` If the expression `$stock{$ky}[0] eq '0'` is true then `$data[9] = ''` else `$data[9] = '0'` poj	[reply] [d/l] [select]

Can you explain $data[$fno$sz] = ( $stock{$ky}$sz eq '0' ) ? '' : '0' ; ? Is it setting the value of the array to 0 or ''? I don't understand the brackets around $sz.	[reply]
