in thread Always leaving one space in file

I tried this with no success:

my $list;
my @changes = param('tellmessage');

######################

if (@changes eq " ") {
  exit
}

######################

open(FILE, ">eetnlinks.txt") || die "Can't open file!";
  flock(FILE, 2) || die "Can't lock file!";
  #truncate(FILE,0);
    foreach $list (@changes) {
      chomp ($list);
      print FILE "$list\n";    
    }    
close(FILE);

Or could I count the length of @changes and compare it: 
if (@changes > 1) {
  exit;
}

If that would work, I don't know how to count the length of the string... ?

    Try not opening the file unless you have data in the @changes array: 
    if (@changes) {
   # do stuff here
}

    my $length = length $some_string;

    Why do you insist on a list? Does the tellmesage parameter contain multiple values? If it was a textarea than it contains just one value and you can retrieve it with: 
    my $change = param('tellmessage');

      It is a TEXTAREA not a TEXTBOX

      There is one link perline separated by a pipe "|"

      I tried using $change, but it wouldn't work :(

        A textarea is just one value - exactly like textbox. Just try the example presented in the pod for CGI (perldoc CGI) and changet the textbox to textarea - everything will work.

    what I meant was: 
    if (@changes eq " ") {
  @changes eq ""}
}
