Name
repeat with {loop variable} from {integer} to {integer}[by stepVal] end [repeat]
Syntax
Repeat with loopVar from 1 to 10 (* code statements *) end repeat
Description
This form of the repeat
loop executes a specified
number of times over a range of values. A loop variable keeps track
of how far the repeat
loop has progressed in
cycling over its range of loops. The loop variable increments by the
value of stepVal
(or one by default if the
stepVal
variable is not specified) throughout each
loop. This makes the repeat with
statement much
more flexible and powerful than repeat {integer} times.
You can take the value of the loop variable and use
it in the executing code, as in the following example. Once this
repeat with
statement reaches the end of its
range, as in:
repeat with loopVar from 1 to 10
(10 is the end of the range here), then the repeat
loop terminates and code execution resumes with the statement
following end repeat
. You can also use the
exit
statement to terminate this loop (see
“exit”). repeat with
is similar to the famous:
for (i=0; i < rangeVar; i++)
variation of the loop statement that JavaScript, Java, and C++ programmers are very familiar with.
Examples
This AppleScript loops through each character of a word to see if any character is repeated. It uses the loop variable to determine which character in the word to examine. This example also shows how you can specify any of the range values with expressions that return integers, instead of just literal integers:
repeat with ...
