I just copied Dave’s code into a blank report and it compiled just fine.
That said, this utility that I presented at the User Conference last year that offers an alternative approach to Dave’s code. Instead of writing out to text file, the information is recorded in a VBA data provider of a BusObj document. That way you have all of the reporting capabilities of BusObj. You may also have some interest in the code itself as an “academic” exercise.
