Here is a sample of what you will find in lesson 21 of the downloadable Tutorial on Excel macros
Lesson 21 on Excel Macros (VBA):
VBA Code for Functions
There are three topics in this lesson:  using Excel functions within macros,  using VBA functions within macros,
 creating new Excel functions with VBA.
Excel Functions
Some of the functions that you find in Excel are available through macros in this form:
Range ("C1").Value=
Application.WorksheetFunction.Sum(Range("A1:A32")) this sentence sums the values of cell A1 to A32 and stores the total in cell C1.
VBA Functions
Here
are two VBA functions that you will use within your Excel macros:
LCase, UCase
The " If" statements are case sensitive. When
you test a string of characters and you do not know if the user will enter upper case or lower case letters, use the LCase or UCase functions within your " If" statement so that however the user enters his answer the statement will work.
If
LCase(Selection.Value)= "yes" then...
or
If
UCase(Selection.Value)= "YES" then...
