Adding page coding in Bar39

[annp61759247]

I have a scanner that reads barcodes on pages but I need to print my documents with the barcode on them. 

I can get very close with bates numbering inserting the page number but I need to remove the backslash. As shown below, it'll generate a barcode *1/2* but I'm needing a code of *12* or *0102*. For a 3 page document it would be Page 1: *13* or *0103* | Page 2: *23* or *0203* | Page 3: *33* or *0303*. "*" is the start/stop in the reader. 

Can anyone help?
