Apache/mod_rewrite VS. Zeus/rewrite.script

Hi,

Does anyone know how to convert the rewrite script in .htaccess on Apache server to rewrite.script on a Zeus server?

inside my .htaccess file,

RewriteEngine on
RewriteRule ^([a-zA-Z0-9\\-]+)/?$  lw.php?pg=$1 [QSA]

inside my rewrite.script file,

match URL into $ with ^([a-zA-Z0-9\\-]+)/?$         
if matched set URL=lw.php?pg=$1

I tried to looked up rewrite.script for Zeus server, but most of the resource are poor… they dont work basically. this is one of them,

Many thanks,
