Flash MX 2004 Games : Art to ActionScript

Chapter 9: Using loops
Now instead of testing for the case where the loop variable i reaches a certain value, we look
for when the sum gets to a certain value. The ‘for’ loop is best used with a loop variable that
is incremented by a regular amount, usually one, and the test is for the loop variable reaching
a certain value. The ‘while’ loop is best used when the knowledge of the loop condition is
not so closely allied to the loop variable. It is possible with both constructions to create a loop
that never terminates. In such circumstances your computer will briefly hang until Flash realizes
that something untoward is going on and offers a dialog box enabling you to terminate the
use of scripts in the existing program. Here are two obvious examples of loops that will never
terminate:
//Example A
sum = 0;
for (i=0; i1000) then the code block is exited
using the break statement.
