Potentially simple question: How do you get code from servers

I thought there was a way to be able to read the code of servers, or the sqf files specifically. I can't remember how to do, and I spent a little time trying to search, couldn't find it. Sorry if it is somewhere obvious, or fixed.

Thank you

Edit: I might also be completely retarded and just thought you can do this easily. I thought I did it before on Wasteland servers.

you mean their mission file?
