Exit Loop If
Exits a loop if the specified calculation is True (not zero).
Exit Loop If [<Boolean calculation>]
Click Specify to define the Boolean calculation. In the Specify Calculation dialog box, type the calculation you want evaluated, or use the field list (on the left) and the functions list (on the right) with the mathematical and text operators to build the calculation.
This script step is also supported in web publishing and in a FileMaker Server scheduled script.

If the calculation is True (not zero), the script continues with the script step that follows the End Loop script step.
If the calculation if False (zero), the loop is not exited and the script continues with the script step that follows the Exit Loop If script step.
This example calculates a bonus for the top 10 sales agents based on their sales. The script finds all records and sorts by a field called "Sales" (descending) to arrange the agents by sales performance. The script starts at the first record and sets the loop counter variable to 1 (in this example the loop counter field use is a number field with global storage enabled -- this is the Count field in the example below). Then, the script calculates the bonus as one quarter of the agent's salary. The script then goes to the next record and exits the loop if the counter reaches 10. The loop counter increments by 1 and the loop repeats.
