Sets barcode text (ASCII version). 
Specifies the data to be encoded as barcode (also called utilizable data). 
 The codeable strings (allowed characters) depend on the selected barcode type: Some barcodes support alphanumeric and some support only numeric characters. Some require a specific length of the string, some not. If the data provided is not valid for the selected barcode an error is returned in BCCheck(). For a list of codeable characters for a specific barcode type check out the separate document Barcode Reference (http://www.tec-it.com/documentation).
