You already know that you can use subroutines in your macros. VBA also allows you to define functions that can be used in your macros. The difference between functions and subroutines is that functions can return values, whereas subroutines cannot. Consider the following VBA macros:
Sub Macro1() TooMany = TestFunc If TooMany Then StatusBar = "Too many pages" End Sub
Function TestFunc() TestFunc = False If Selection.Information(wdNumberOfPagesInDocument) > 10 Then TestFunc = True End If End Function
There are two macros in this code. One is the function (TestFunc) and the other is a macro (Macro1) that is used to invoke the function. When the function is executed, it can do anything that is done in a regular macro. In this case, it performs a test that results in the TestFunc variable being set to either True or False. Note that this variable name is the same as the function name. This is the value that is returned by the function to whatever program called it.
Which brings us to the Macro1 macro. Note that the TestFunc macro can appear on the right side of the equal sign. This makes functions very powerful and an important part of any program. VBA executes the function and returns whatever value is appropriate from that function and assigns it to the variable on the left side of the equal sign (TooMany). The program then acts upon the value returned.
