World save-file in Developer Help

I've always been really weak on save-files, and a several-year absence from BYOND hasn't helped!

I want it so that whenever I close the program running the world that several vars are saved to a file, and the moment I run it again they're loaded back in. It sounds simple but I'm not sure where to start!

Thanks in advance for any advice!

How do you declare world vars?! I tried

world/var/turn


and was treated to this error message:

Vars.dm:3:error:turn :variable declaration not allowed here

How come?

<edit>I've now tried the following, but it's failing. Ungh!

world
        
    New()
        ..()
        var
            Turn  // The current turn
            Phase // Current Phase, 1=Attack, 2=Defend, 3=Results
        var/savefile/F = new("World")
        Read(F)
            
    Del()
        ..()
        var/savefile/F = new("World")
        Write(F)

Take the world part out.

Just;

var/turn


I'm going to let you figure out how to do the saving and loading part ;)

Reference/Guide are your friends, by the way.
