Swapping Two Numbers

Summary: When developing a macro, you may need to swap the values in two variables. It's simple to do using the technique in this tip. (This tip works with Microsoft Word 97, Word 2000, Word 2002, Word 2003, and Word 2007.)

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.

Tip #738 applies to Microsoft Word versions: 97 | 2000 | 2002 | 2003 | 2007
