Argument descriptions

When you access a built-in function from the Insert Function dialog box, the Function Arguments dialog box displays a description of each argument. (See Figure 21-5.) Unfortunately, you can't provide such descriptions for custom functions. You can, however, make your argument names descriptive — which is a good idea.

Figure 21-5:

The Function Arguments dialog box displays function argument descriptions for built-in functions only.

This chapter provides lots of information about creating custom worksheet functions. Use these examples as models when you create functions for your own work. As usual, the online help provides additional details. See the next chapter if you want to find out how to make your custom functions more accessible by storing them in an add-in.
