oh ok.
it seems like you would need to use the FSO, then put that all into a string, and use some Replace functions and/or mid functions to take out/put in what you need.
once you're done with that, you would need to rewrite the whole file again.
If you're appending to the file, though, you just need to open the file up with the 8 (for appending), then append unto the end of the file.
I don't know if I'm helping at all... why not post an ex of your file, then what you want the file to look like afterwards.
