^ Syntax | (or exp1 [exp2 ... expn]) -> value/Nil |
^ Arguments | exp1: An expression that evaluates to **Nil** or something else |
^ [exp2 ... expn] | Additional expressions to be evaluated |
^ Category | [[logical operator functions|logical operator]] |
^ Returns | The value of the first expression that does not return **Nil**, or **Nil** if there is none. If there is only one argument, returns the value of that argument. |
^ Description | Uses lazy evaluation, which means that it stops after it finds a non-**Nil** value or ends up evaluating every argument if all of them return **Nil** |

=== Example ===
<code>
(or 1 2 3 4 5 (setq foo 6))
</code>
Return **1**. Also, foo will not be set to **6**.

<code>
(or Nil (eq (setq foo "bar") "baz") "qux")
</code>
Returns **"qux"**. Also, **foo** will be set to **"bar"**

<code>
	(errblock (error b)
		(setq b (or c 0))
		b
		)
</code>
If **c** has not been bound anything, then this code will return the error **No binding for symbol [c] ### (or c 0) ###** since errors are not **Nil**. Beware of bad code when using **errBlock**, as **or** will simply evaluate the thrown errors as **true**
