This variable contains the code string from which the barcode is to be created.
In the present context this data is passed as the sIn parameter to either BarCodew() or BarCodewF() and so should NOT be passed directly to the BARCODE structure.
Note that in barcodes the difference between upper and lower case letters is significant. Few coding schemes support lower case letters. Also note that when calling from Visual Basic this item is dimensioned in Basic as an array of 80 bytes - not a Basic string.
