Hi SUIYAN,

I'm not sure that I am following what you mean about a delimiter. Perhaps you are misunderstanding that in javascript, statements can be continued over multiple lines? (the purpose is to make the code more easily read and understood)

Also, I noticed that you deleted a couple of the commands from the list (Flip and IncrementalSave) so I put them back in. See the attached file.

The lines beginning with - are the original lines, those with + are the modified lines.
