The lion's share of Bruce Perry's treatment of the language explains, with a minimum of frills, how each aspect of the AppleScript language works. This is classic O'Reilly, and it works well. For each statement (such as "with transaction") and reserved word (such as "anything"), you get a concise statement of syntax, examples of proper usage, an explanation of what's going on, and caveats where they're required. Classes--the one that the Finder uses to represent folders, for instance--are presented with each of their properties and methods listed alphabetically, and explained, usually with an example. The scripting techniques that are specific to applications, such as Sherlock 2 and the Speech Listener--are similar, with commands and classes presented alphabetically with all options presented explicitly. This book is a comprehensive treatment of a really useful language. Check out Learning Carbon and Learning Cocoa if you want to delve deeper into Mac OS programming. --David Wall
