Editing Macros

Taking a look at the programming code used in a macro (either ones you have recorded or macros created by others) is a great way to help you understand how the macro is put together and how it works. You can do this examination, and make changes to your macros, by editing them. To edit a macro you first need to display the Macro dialog box. The easiest way to do this is to simply press Alt+F8. (See Figure 1.)

In the list of available macros you should choose the macro you want to edit. When you have selected one, you can click on the Edit button and the VBA Editor is displayed with the selected macro loaded and ready to edit.

Once your macro is displayed, you can make changes to it as desired. You use many of the same editing functions you use when making changes to a regular worksheet. Unless you fully understand the consequences of your changes, it is typically best to stick to recording simple macros. If you feel adventurous, however, there is nothing wrong with making changes to your macros to see what they will do. If you do so, it is a good idea to keep these tips in mind:

• As you are developing and testing macros, always use copies of your data. Keep the original data stored in a safe place.
• Keep a good macro language function reference or command reference close by.
• Test often as you make changes. Don't make all your changes at once and then expect to perform one test and have everything work. Unfortunately, life is not that simple.

If you keep these tips in mind, there is very little chance that you will hurt anything. In fact, your chances of learning more about Excel and macro programming are much greater than the risk of damaging any data. Give it a try!

When you have finished making changes to your macro, you should close the VBA Editor. Closing the VBA Editor is done in the same manner as when you close any other Windows program—simply click on the Close icon in the upper-right corner of the window.
