How to Make Objects Send Data to Each Other?

I'm an educator new to scripting. I want to create objects that can send data back and forth - too many variations to go into here. What are the basics for this -the functions I should look at, examples, etc.? Thanks!

Assuming the objects are not linked, use llSay, llShout, or llWhisper to send information and llListen combined with the listen event to receive information.

All of the functions require a channel parameter which you can set to a non-changing number (preferably negative).

It is possible for others to eavesdrop on the communications between your objects, so assume the worst and design for high security.

Look at the functions on this page: http://www.lslwiki.org/index.php/Communications

Also the table shows some scenarios to help you choose which method to use. The formatting is funky because this is a backup of the original page.

If you want more security than the offered with llSay, llWhisper and llShout, you can use llEmail or, for me even better, llHTTPRequest with an external database.
