Exercise: Recursive programming

A full answer to this exercise is provided as part of the training course!

1)	In any application (Word, Excel, PowerPoint or whatever) write a macro which calculates the factorial of a number.  Your macro should use recursive program calls.
The factorial of 4 - often written as 4! - equals 4 * 3 * 2 * 1.
2)	Save this file with a suitable name, then close it down.

Thank you for showing an interest in this Advanced Visual Basic for Applications training course! As mentioned above, full answers to this and other exercises are provided on the course. On all Wise Owl scheduled courses delegates can take away these model answers (together with their own efforts!) on a free USB stick.
