Aprogram to illustrate exceptional handling

You surround your part of the program that can throw exceptions with a

try { ... } block and place a catch(...) { ... } directly below it.

You could put code in the try block that divides by zero to see an exception in action. Alternatively, you can throw one yourself using the throw keyword.

so much for the extra points :

a macro is a tool that allows you to automate tasks and add functionality to your forms, reports, and controls. for example, if you add a command button to a form, you associate the button's onclick event to a macro, and the macro contains the commands that you want the button to perform each time it is clicked.
