Can point me towards this and a tutorial? Please?
Ezscript comes with ffx 3.3. It's not a program, but a function.

Benton also did a break down or two: http://bentongrey.wordpress.com/2010/01/18/the-ease-of-ezscript/ and http://bentongrey.wordpress.com/2010/01/21/the-anatomy-of-an-ezscript-adventure/ and http://bentongrey.wordpress.com/2010/01/26/doing-more-with-ezscript/
Edit: i almost forgot about M25's Ezscript Editor (http://ezscript.wikispaces.com/Mod+Tools), which really simplifies the process of making EZScript mods. Goggles also has a web based verse here (http://gpwarehouse.freedomforceforever.com/ezassist/), but m25's tool is the go to editor as of now.
