do while

do loop while (condition);

•	loop	–	Executes once, then executes condition.
•	condition	–	If condition executes true, it then loops back and executes loop again.

Any of the statements can be null statements. A do...while loop is slightly faster than a while or for loop, and requires fewer bytes of memory than a while or for loop.

Specification

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

Examples

//Counts from 1 to 5
default
{
    state_entry()
    {
        integer olf;
        do
            llSay(0, (string) (++olf));
        while(olf<5);
    }
}

//Counts from 0 to 4
default
{
    state_entry()
    {
        integer olf;
        do
            llSay(0, (string)olf);
        while((++olf)<5);
    }
}
