•	condition	–	If this executes as true then loop is executed.
•	loop	–	Can be either a single statement, a block statement, or a null statement.

Any of the statements can be null statements.

**Conditional Types**
Type	Condition
integer	True if it is not zero.
float	True if it is not zero.^[1]
string	True if its length is not zero.
key	True only if it is a valid key and not NULL_KEY.
vector	True if the vector is not ZERO_VECTOR.
rotation	True if the rotation is not ZERO_ROTATION.
list	True if the length is not zero. Note that correct behavior is only seen with Mono-compiled scripts; LSO-compiled scripts incorrectly resolve to false if the list is non-empty: BUG-230728

<lsl> //single statement integer a = 0; integer b = 10; while(a < b)

   llOwnerSay((string)(a++));

</lsl> <lsl> //block statement integer a = 0; integer b = 10; while(a < b) {

   llOwnerSay((string)a);
   ++a;

} </lsl> <lsl> //null statement integer a = 0; integer b = 10; while(a++ < b); </lsl>

A do-while loop is faster than a while loop or a for loop in LSO.

^ The OpenSim LSL compiler will not do this implicitly. You will need to use an explicit check.
