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.

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);
    }
}
