AppleScript has a few predefined variables that are mentioned and used throughout the book. These variables are as follows: return, which has the value of a return character space, which has the same value as a space character tab, which has the same value as a tab character quote, which has the same value as a straight double quote pi, which has the real value of 3.14159265359 minutes, which has the value of 60 seconds hours, which has the value of 3600 seconds days, which has the value of 86400 seconds weeks, which has the value of 604800 seconds

The variable it describes the object currently targeted by a tell block. In Script 8-14, the value of it is document 1 of Script Editor: Script 8-14. tell application "Script Editor" tell document 1 display dialog (text of it) end tell end tell The value of me is always the current script. You can use me in the Standard Additions path to command to get the path to the script s file or applet, although this doesn t work in all applications: path to me You can use me within an application s tell block to direct handler calls to the script itself instead of the targeted application. For example, the following script will raise the error Can t continue do_this_thing when it attempts to call the do_this_thing handler from within the tell application block:

Using result
The result variable contains the result of the last statement that ran, provided that the last statement returned a result. In the following example, the value of the result variable will be 12 after the first line and 36 after the second line: 5 + 7 result * 3
CHAPTER
Introducing Operations and Coercion
ook around you, and you will find that the environment in which you script is chock-full of raw material numbers, text, data, dates, and other values taken from files, documents, web pages, databases, and user input. All these values won t amount to anything without you molding them into something else. In fact, a large portion of scripting is taking values, changing them, and forming new values to your liking. Since operators and operations are everywhere in AppleScript, they are covered extensively throughout the book. You will mainly find operations covered in the chapters devoted to numbers and math, text and strings, dates and time, and so on. This chapter aims to tie up the loose ends but not to cover what is extensively covered in other, more targeted chapters.
What Are Operations
As the AppleScript Language Guide describes it, Operations are expressions that use operators to derive values from other values. In simple terms, operators are tools for manipulating data. Operations turn flower, milk, and sugar into pancakes; a few words into a sentence; some numbers into a meaningful result . . . you get the picture. In the pancake s case, the ingredients are the operands, the mixing is the operator, the mixed batter is the expression, and the steaming pancake on your plate is the result. Although AppleScript doesn t have operators that can be used for cooking, it does have operators for comparing values, doing math with numbers, performing Boolean operations, calculating dates and times, and doing much, much more.
