It's an enumeration (a variable that can have one of a list of values). They're nicer than things like include files so you can have meaningful values instead of numbers - think about the parameters in MESSAGEBOX in VFP:

MESSAGEBOX("Hello", 64, "Title")

You could use a value from a header file in the above code.

In .NET you can use an enumeration (which is nice since it shows you the allowable values and you get intellisense):

(this is the .NET equivalent):

MessageBox.Show("Hello", "Title", MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1);
