Not long ago I had a client that was using a barcoded coversheet to replace a previous version that required OCR.  The client placed several values into the barcode with a delimiter and wanted them parsed out and placed into the appropriate index fields.

Recognition Script seemed like the most likely place to implement this little tidbit of code.  Unfortunately I quickly found out that while I could parse the barcode into its separate values, Recognition Script only provides access to the index field its applied to.  Therefore I had no access to the other index fields and could not set them.
