# Server variable system

The **server variable system** (put short, **SVar**) is a new way of creating global server variables efficient and dynamically, meaning that they can be used in server's gamemode and filterscripts at the same time.

They are similar to [PVars](https://omp.itsneufox.com/docs/tutorials/perplayervariablesystem), but are not tied to a player ID.

warning

This system was introduced in SA-MP 0.3.7 R2-1 and will not work in earlier versions!

note

The SVar system is the same as the PVars, although the variables created are server-wide, not attached to any player ID, and persist through gamemode changes.

## Advantages

-   SVars can be shared/accessed across gamemode scripts and filterscripts.
    
-   You can easily enumerate and print/store the SVar list. This makes debugging easier.
    
-   Even if a SVar hasn't been created, it still will return a default value of 0.
    
-   SVars can hold very large strings using dynamically allocated memory.
    
-   You can Set, Get, Create SVars ingame.
    

## Drawbacks

-   SVars are several times slower than regular variables. It is generally more favorable to trade in memory for speed, rather than the other way round.
