the exception handler chosen is said to "catch" the exception. If the runtime system cannot find an appropriate exception handler even after searching through the entire call stack, the operating system generates a fatal exception message, which means that the program must close and perhaps the s...

Exception handling is useful for dealing with exceptions that cannot be handled locally. Instead of showing an error status in the program, theexception handlertransfers control to where the error can be handled. A function can throw exceptions or can choose to handle exceptions. ...
The runtime system searches the call stack for a method that contains a block of code that can handle the exception. This block of code is called an exception handler. The search begins with the method in which the error occurred and proceeds through the call stack in the reverse order in...
If the Undo command is taking too long to complete, it could be because you've exceeded the program's limit for undo actions, or because the action itself was very complex. In this case, you may need to wait a bit longer or, if that fails, close the program (some work might be lo...
