Ed Dillinger: What's the project you're working on?
Alan Bradley: Well, it's called Tron. It's a security program itself, actually. It monitors all contacts between our system and other systems. It finds anything going on that's not scheduled, it shuts it down. I sent you a memo on it.
Ed Dillinger: Part of the Master Control Program?
Alan Bradley: No, it'll run independently. It can watchdog the MCP as well.
Quotes from Bruce Boxleitner movies and TV shows
Ram: You really think the Users are still there?
Tron: They better be. I don't wanna bust out of here and find nothing but a lot of cold circuits waiting for me.
Kevin Flynn: Alan?
Tron: Where did you hear that name?
Kevin Flynn: Well that's your name, isn't it?
Tron: The name of my User. How did you know?
Kevin Flynn: I'm a program from a User that knows Alan.
