Darren,

Seems like the scanner would be looking for an x'0D' and/or x'0A'.  If I
remember correctly, if you encode x'0D25' into your ebcdic string, it
will be converted to x'0D0A' by the ebcdic to ascii conversion table.

So, 
eval barcode = %trim(barcode) + x'0D25';
might do the trick.

Incidentally, would you mind telling me what print mechanism you are
using to print the 2D barcodes?  I was just reading the other day that
host print transform is incomplete in that it will transform and print a
1D barcode, but not a 2D barcode (as of V5R2).  Has that limitation been
removed, or are you using an IPDS printer of some kind?
