Hi Chris,

thanks for your help and work. But now, i don't  know what make to do. I 
noticed your last message with the vb script. You can send me the script 
and i attempt to test it with the latest version of mkgmap, but i use a 
linux-server for rendering, i hope, it works out. My email address is:

Cheers,

Michael
