The exceptions thrown in such modules can be caught and handled in PowerShell script and visa versa. For example, in C++: "Exceptions are run-time anomalies, such as division by zero, that require immediate handling when encountered by your program". Any value may be used.

If no active TRY is found after throwing an exception, then an unhandled exception message is printed to stderr, all processing is terminated within the current CMD shell, and control is in the "past". If an exception is thrown, the batch CALL stack is popped repeatedly until it reaches an active TRY block, at which point control is passed to the associated CATCH block and Batch File Errorlevel A series of exception attribute variables are available to the CATCH block: exception.Code - The numeric exception code exception.Msg - The exception message string exception.Loc - The string describing the location

While returning from a recursive call, it throws an exception if the iteration count is a multiple of 3 (iterations 3 and 6). I likely will not update this StackOverflow post.
