To remove a variable, set it to nil (e.g. player setVariable ["varname", nil];).

All available data type combinations:
Arma 3 logo black.png
In Arma 3 it is possible to broadcast nil value
Multiplayer:
The variable space of the object is local to each client and by default changes are not broadcast.
Since Arma 2: If the public parameter for supported types is true, the value will be synchronized also for a JIP player.

Syntax

Syntax:
objectName setVariable [name, value, public]
Parameters:
objectName: Object or Location. Arma 2 also supports: Namespace, Group, Control, Task
[name, value]: Array
name: String
value: Anything (if public is true, check publicVariable for what types are supported for broadcast)
public (Optional): Boolean - Only available for Object types and (since Arma 1.48) for missionNamespace. If public is true then the value is broadcast to all computers.
Return Value:
Nothing

Examples

Example 1:
_myTruck setVariable ["myPublicVariable", 123, true];
Example 2:
_myTruck setVariable ["myLocalVariable", ["321", _var], false];
Example 3:
missionNamespace setVariable ["myName", "KK"]; hint myName; //KK

According to Suma, beginning with ArmA version 1.08, "setVariable now should work on any entity which can be targeted by AI, including soldier and game logic units. This includes most buildings, but not other static objects. Using it with buildings one should be aware the building may be discarded because of streaming. In such case the variable space is lost. When used for buildings, the storage should therefore be considered non-reliable." Reference: Make setVariable work on other things than just vehicles

Public variable parameter works also for groups in ArmA II. Ref: A2 CIT.

In Arma 2 1.05 the missionNamespace object allows only the two main Arguments by syntax. Publishing the Variable afterwards works fine.

IMPORTANT: This will not work on groups if you do it from the init line (you'll experience locality issues). Do something like this instead: Put this on init line: b_GroupSetup = [ group this, "3/B", "Tank", "Platoon"] execVM "grouptest.sqf"; grouptest.sqf: if (isServer) then { private ["_GroupSelect", "_GroupDesig", "_GroupType", "_GroupSize"]; _GroupSelect = _this select 0; _GroupDesig = _this select 1; _GroupType = _this select 2; _GroupSize = _this select 3; _GroupSelect setVariable ["groupDetails", [_GroupDesig, _GroupType, _GroupSize, 0, [], ""], true ]; };

(A3) Disable randomization and set a color to randomized vehicles by using ‘this setVariable ["color",X]’ in the init of the vehicle where X is a number ranging from 0 to the number of skins (minus 1). If the number is out of range, the skin is still randomized.
