Swapping Two Numbers

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 leave you 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.

ExcelTips is your source for cost-effective Microsoft Excel training. This tip (2525) applies to Microsoft Excel 97, 2000, 2002, and 2003. You can find a version of this tip for the ribbon interface of Excel (Excel 2007 and later) here: Swapping Two Numbers.

What is three more than 8?

Another method without using a helper variable...

A = A Xor B

B = A Xor B

A = A Xor B

Notice the expression to the right of the equal sign is the same for each of the three steps making it easier to remember :-)

The solution offered by Ioannis works only for numbers, of course. The first tip is simple and straightforward. Most code can afford an extra variable in order to provide some simplicity. KISS.

Another interesting approach (without the helper variable:
MyNum1 = MyNum1 & "," & MyNum2
MyNum2 = Split(MyNum1, ",")(0)
MyNum1 = Split(MyNum1, ",")(1)

A solution without the help of another variable:
MyNum1=MyNum1+MyNum2
MyNum2=Mynum1-MyNum2
MyNum1=MyNum1-MyNum2
