If you do any serious macro programming, there will eventually come a time when you want to swap the values in two numeric variables. In some versions of BASIC, there are commands that handle this. VBA leaves us to our own devices, however. The following technique should do the trick for most people:
TempNum = MyNum1 MyNum1 = MyNum2 MyNum2 = TempNum
When completed, the values in MyNum1 and MyNum2 have been swapped, and TempNum doesn't matter since it was intended (by this technique) as a temporary variable anyway.

Long ago when memory was a scarce and expensive ressource, I used to swap two numbers without using a temporary variable, as follows :
MyNum1 = MyNum1 Xor MyNum2
MyNum2 = MyNum2 Xor MyNum1
MyNum1 = MyNum1 Xor MyNum2
You can check that it actually works!
