A do loop has this form:

do {

	statement;

	statement;

 ...

} while (condition);

Unlike the while loop, a do...while loop checks the condition at the end of each cycle. The block will execute at least once. The loop terminates when condition is false.

float $test = 0;

do	{

	print("$test equals: " +$test+"\n");

	$test = $test + 1;

	} 

while ($test < 5);

This prints the following lines in the Script Editor:

$test equals: 0

$test equals: 1

$test equals: 2

$test equals: 3

$test equals: 4
