You can place debugger statements anywhere in procedures to suspend execution. Using the debugger statement is similar to setting a breakpoint in the code.
The debugger statement suspends execution, but it does not close any files or clear any variables.
The debugger statement has no effect unless the script is being debugged.
This example uses the debugger statement to suspend execution for each iteration through the for loop.
To run this example, you must have a script debugger installed and the script must run in debug mode.
