The assignment operator is the only operator that isn't really an operator. It is a special construct.<br />
Take for example, the following expression:
<code>hello + 5</code>
Assuming ''hello'' contained the value ''10'', ''hello'' would evaluate to ''10'', and ''10 + 5'' would finally evaluate to ''15''.<br />
<br />
Which is why the assignment operator wouldn't work as a regular operator.<br />
Take for example, the following expression:
<code>hello &#61; 10</code>
If the assignment operator was a regular operator, ''hello'' would first evaluate to ''[[nil]]'' and finally ''nil &#61; 10'', which wouldn't make a whole lot of sense.<br />
<br />
To work as a regular operator, and like any other operator requiring a reference to a variable rather than the variable's value (Eg. [[isNil]] and [[publicVariable]]), its syntax would have had to be.
<code>"hello" &#61; 5</code><br />

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"
