The five characters that make up the word (a,p,p,l,e) are all objects based on the BBEdit character class. So a word object constitutes a group of character objects. If you grouped together several separate character objects they might look like ("a", "p", "p", "l", "e"). " It is always important to describe an Apple event object in your script by its containment hierarchy, which is an exact specification of where an application like the Finder can find the object. Apple event objects are located in a similar manner to taking apart one of those wooden Russian dolls, where the dolls get smaller and smaller until you finally locate the last solid peanutshaped doll inside of all the bigger ones.
2 Apple Event Registry Along with scripting components, another important OSA element is the Apple Event Registry. The Registry is an Apple Computer-maintained database that maps all of the Apple events that the Mac OS standard software uses to a corresponding English-language command. This means that the activate AppleScript command is mapped to an activate Apple event, quit is mapped to a quit Apple event, and so on. You can use the Registry to discover the Apple event codes that are used by the Mac's standard software (such as the Appearance control panel, the ColorSync extension, or Sherlock 2).
8 Operators and Reference Forms An operator is a symbol or token that is used with values or variables in an AppleScript expression. An example is the well-worn expression 2 + 2 = 4 (if you just dropped this expression into a Script Editor window, it would return a boolean value of true). The operators in this expression are "+" and "=". AppleScript has most of the operators that you would expect a scripting language to make available to the programmer. AppleScript also allows the scripter to use very readable English expressions for operators, such as: if 5 is greater than 3 and 6 equals 6 then set bool to true The principal symbolic operators are demonstrated in Example 1-10.
