Forums Scripts & Popups Reading multiple lines in a script?

Ah, I didn't mean that. For example, let's say there's an ON Text event and I wanted to see the last X lines before that text event (given that I was in the channel at the time). Or I want to have an ON Text event and get the lines that come after that one.

Essentially, I want to be able to manipulate/use more lines from the channel than just the one that triggers the event.
