Why does the script do /r/n at the end of the line?

Question

Mikrotik

:local listName "rdp_blacklist"; 
:local fileName "test.txt"; 

:local script2write  "
  :local counter;
  :foreach counter in= [/ip firewall address-list find list=$listName] do={
    :local ip [/ip firewall address-list get \$counter address];
    :put \$ip;
  };
";
:put $script2write;
:execute script=$script2write file=$fileName;

at the end of each line / r / n, I don’t understand where it comes from, I need there to be no transfer, tell me plz
