Assigns the result of expression on the right to the variable on the left. Technically this is not a command and it is not listed in supportInfo; this is more of a compiler instruction.
The following structure is invalid: a = b = c = 4;


variable = value
variable: Anything - see Identifier
value: Anything
Return Value:
The returned value is not equivalent to nil. See Notes below for additional information.


Example 1:
_value = 5
Example 2:
_mygroup = group player
Example 3:
_greeting = "Hello!"
Example 4:
private _enemyTank = myTank1

A conditional assignment can be done via the following syntax: _msg = if (alive player) then {"you're alive"} else {"you're dead"}

It's possible to assign to numbers. Numbers values are not changed. Useful instead of assigning to nul or nil when a result is of no use. 0 = [player] execVM "myScript.sqf"

This operator actually does not return a Nil. It really returns pure Nothing. Not Nil Nothing.
This can cause problems. For example: _var1 = call { _var2 = ""; }; The return value of the "call" is the return value of the "=" operator.
If it were a nil then of cause "_var = nil;" would work just fine.
But in reality this causes a "Generic Error in expression" because you can't assign pure Nothing to anything.
