Note that the temporary variable (`ic` in the example) represent an iterator of the `ITERABLE` object, and not directly an element like in many other languages (like the `for` structure in Python for example).

[[Property:title|Managing CTRL+C in console application]]
Normally, if the user use the CTRL+C keys, the Eiffel application detect it as an error and throw an exception of type <code>OPERATING_SYSTEM_SIGNAL_FAILURE</code>.
Normally, if the user uses the CTRL+C keys, the Eiffel application detect it as an error and throw an exception of type <code>OPERATING_SYSTEM_SIGNAL_FAILURE</code>.
To manage the CTRL+C keys, you can use a <code>rescue</code> clause to detect the exception and a <code>retry</code> mecanism to cancel the exception handeling done by the Eiffel runtime.
To manage the CTRL+C keys, you can use a <code>rescue</code> clause to detect the exception and a <code>retry</code> mechanism to cancel the exception handling done by the Eiffel runtime.
To detect the exception, you can <code>inherit</code> from the <code>EXCEPTIONS</code> class and use an attachment test on <code>Exception_manager.last_exception</code>.
Note that this code does not work on Windows. If used on Windows, the application will quit, but the <code>rescue</code> call is not launched.
