I need to make a mod with a custom dvar such as g_gravity 1.

Exactly, how do I do this? I know very, very little about modding.

I suppose I'll answer this.... * 6 months later *

1. You don't need to make a mod for this.
2. It's not a custom dvar, it already exists.
3. Not only do you know very little about modding, but it may be the same for cod4...
MEANING...

Login to the server if you are the admin.
Do this by typing into the console:
/rcon login password (replace 'password' with your pass)
Then type /rcon set g_gravity 1

Ta-da

If g_gravity was an example of a dvar and you want to add a new one, then more info of how its being used would be useful. Typically you add something like

if(getDvar("my_newDvar") == "") setdvar("my_newDvar",1);

to your code in order to initialise it. You then use the dvar like:

if(getDvar("my_newDvar") == 1)
{
   // Do Stuff
}

shouldnt it be if(getDvar("my_newDvar") == "") setdvar("my_newDvar";1); instead of the , in front of the 1 at the end?

No, A semicolon (;) , Indicates the end of a code.

Correct Insane - comas are used to separate arguments in functions, of which setdvar is one.

or you use a semicolon in a " for " loop

for( i=0; i < 20 ; i++ )
