Is the above "cycle" a special handler? If not, what causes it to repeat?

This is a plain ordinary handler.

Note that its name is "cycle". (It can be anything.)

Then, in the body is a send:

send "cycle" to me in 333 milliseconds

That puts "cycle" (back) in the pending message queue. Revolution will execute the message in a third of a second (333 milliseconds).

So, what cycle does is 1) make any changes needed to the state of your application and 2) ask Revolution to run it again in a third of a second.

This line saves away a reference to the pending message so it can be cancelled, breaking the cycle:

put result() into flashingID

You can use units of seconds instead of milliseconds if you want.

After execution cycle the application has this change: The changes made by the change handler are done. (That can be inline if you want.) The handler is scheduled for (re)execution. An ID for cancelling is remembered.

(I knew you have the digest and should have slowed down my responses. Sorry about that.)
