WD97: Writing Macro Code for VBA and WordBasic Branching

MORE INFORMATION

In Microsoft Word 97 and later versions, WordBasic has been replaced with Visual Basic for Applications. For backward compatibility, Visual Basic for Applications contains a WordBasic object. To ensure that the WordBasic command and arguments are positioned correctly, use the Position.hlp file for Word for Windows version 6.x.

NOTE: If your programming language was written to call WordBasic commands and you are anticipating interacting with the Microsoft Word Visual Basic for Applications language for all future development needs, you should convert your code from WordBasic to Microsoft Word Visual Basic for Applications.

Microsoft provides examples of Visual Basic for Applications procedures for illustration only, without warranty either expressed or implied, including, but not limited to the implied warranties of merchantability and/or fitness for a particular purpose.

   ' The GetWordVersion routine creates a WordBasic object. It then
   ' determines the currently installed version of Word for Windows.
   ' If the version is earlier than Word 97, it branches to use a
   ' WordBasic Code" routine.
   ' If the version is Word 97 or later, it branches to use a Visual
   ' Basic for Applications routine. If Word is not currently installed,
   ' an error is trapped and the program displays a message and ends.
