Link to this file MOD challenge

[carefree]

Im trying to create this simple mod , so whenever a new file show it displays the relevent code  inside the textbox area, allowing other site owners to insert the code into thier pages:

 

<b>Link to this file!</b><br />

<textarea rows='5' cols='40' style='font-size: 9px; font-family: Verdana;'><a target=_blank href="{CONFIG_DOMAIN}directory/{FILE.SWF}/">{FILE_NAME}</a></textarea>

 

I just need help with the {} parts, is there  common tags for all sites

 

Thanks in advance
