[3.5 b1] new variables?

[MaTraX]

Hi
Could someone tell me what are new variables that are instead of these ones?

PHP Code:

$tableprefix     = $usersystem['tblprefix'];
$cookietimeout   = $usersystem['cookietimeout'];
$cookieprefix    = $usersystem['cookieprefix'];
$cookiedomain    = '';
$cookiepath      = '/'; 

I will probably have further questions after this one
Thank you in advance for help

i would suggest you to read the How To's...:
