How do I have multiple array (number is variable) events using jass?

I think it is possible using something similar to the integerA action but I don't understand it.

I want to have a trigger fire to the event Timer Array Variable expires.

But i have no idea how big the array can get so I can't add multiple events per timer.

I think it's something with local integers and loops but I'm not sure.

Can anyone help me come up with the JASS code? It would be nice if you can type it up word for word so I can copy it. Just the InitTrig part of the trigger where it adds events, conditions, and actions. Everything below the:

: in a converted trigger.

Your question belongs in the JASS forum there someone will be able to help you.
