different workareas

System

Hi,
How can we code in a tpl so that the workareas in a particular branch are dynamically substitued when giving the code like this, for eg...

URL=http://gcm-vvvv.it.net/iw-mount/default/main/vvvv/WORKAREA/$wkarea/ja_JP/products.cfm?product=ja_JP/$dcrName'>";

thanks in advance..
