Data Types

The data type of a variable specifies which data it may contain. Certain operators and scripting commands require variables to be of certain types.

Definition

The data type of a variable depends on the value given to it on initialization.

myVar = ""; // myVar is now a String

a local variable should be prefixed with private (Arma 3) or local (Arma 2) to avoid a potential upper-scope variable overwrite:

private _myLocalVariable = "";	// Arma 3
local _myLocalVariable = "";	// Arma 2

Redefinition

The data type of a variable may be changed at any point of the game by just redefining the variable with another type.

myVar = "";	// myVar is a String
myVar = 0;	// myVar is now a Number

Magic Types

There are some magic data types, which are not really datatypes, as they do not describe any particular value.

• Any Value
• Anything
• Nothing
• Void

Syntactical Helper Types

Some more types are used to provide for a construction of syntactically richer constructs than normal unary / binary operators.

• If Type
• While Type
• Switch Type
• For Type
