This repeat flavor also allows you to play with the way the repeat variable increases or decreases. You ll see a few examples in the following sections.

As you may imagine, you can use any integers stored in variables to specify the start and end of the range, as shown in Script 11-3. Script 11-3. repeat with n from start_integer to end_integer --do something with n... end repeat This is useful when you don t know in advance the range of numbers you want to count over. This is one of the most widely used variations of repeat loops and is useful when you need to perform a certain operation on a range of application objects for instance, all the pages of an Adobe InDesign document, the records in a FileMaker Pro found set, or all the files in a particular folder. For that, you use the repeat loop along with the count command. The count command along with the object range returns the number of applicable objects, which in turn becomes your repeat loop s number of repetitions. Figure 11-5 shows an example of this. In the example, the script needs to add the word folder to the end of the folder name.

The first variation of this repeat loop flavor lets you change the increments by which the loop variable increases. In the previous examples, the loop variable increased by 1 each time, but what happens if you want to increase it by another number All you have to do is add the by phrase followed by the increment you want to use. Refer to the example shown in Script 11-4.

Script 11-4. set the_list to {} repeat with i from 1 to 50 by 5 set end of the_list to i end repeat the_list = {5, 10, 15, 20, 25, 30, 35, 40, 45, 50} The following example will change every third word in the front TextEdit document into the word carrot: tell application "TextEdit" tell document 1 repeat with i from 3 to (count every word) by 3 set word i to "carrot" end repeat end tell end tell Make sure not to run this script if the front TextEdit document has something important in it, such as a recipe for a carrot cake. If you take this concept a step further, you can create the entire multiplication table, and what the heck, let s present the result in HTML (see Script 11-5). Script 11-5. 1. 2. 3. 4. 5. 6. 7. 8. set set set set set set set set html html html html html html html html to to to to to to to to "" html html html html html html html & & & & & & & "<html>" & return "<head>" & return "<title>Multiplication table</title>" & return "</head>" & return "<body>" & return "<table border=1 cellpadding=2>" & return "<tr>" & return

9. repeat with i from 1 to 10 10. repeat with j from (1 * i) to (10 * i) by i 11. set html to html & "<td>" 12. set html to html & j 13. set html to html & "</td>" 14. end repeat 15. set html to html & "<tr>" & return 16. end repeat Although this is quite a complicated loop, it demonstrates a specific form of repeat loop; you can also achieve the same result in other ways. Here are two repeat loops nested one inside the other. The outer repeat loop simply counts from 1 to 10, assigning the loop value to the variable i, which becomes the driving force behind the inner repeat loop. The inner repeat loop uses the variable j. What gives j the correct integer value for the multiplication table is that every time the loop executes, the start point and end point move up. Here is the inner repeat statement the way it appears in the code: repeat with j from (i * 1) to (i * 10) by i In the first loop, the value of the variable i is 1, and the inner repeat loop looks like this: repeat with j from 1 to 10 by 1
