Dig,
I think the best way to accomplsh this is to create serialized numbers
in Excel, and then use Mail Merge in Word to create barcode labels.
Please have a look at BarCodeWiz Barcode ActiveX Control, which comes
with a Sequential Number Generator in Excel, and ability to create mail
merge barcodes in Word.
If you need any help, please don't hesitate to ask.
