New smarty syntax in PHPR 5

Hello,

in PHPR 4.2 I often used a self defined function within ListOnLoad Event..
for exampe

Function sys_table_caption()

{

$smarty = new Smarty();

global $smarty;

$smarty->assign("sys_table_caption","what you want");

}
in xx...list.htm I used this smarty-variable with {$sys_table_caption}
How to do that now in PHPR 5
Best regards
