Scanning a PDF417 barcode

Has anyone tried reading the input from a scan of a PDF417 type barcode in 
a RPG program? 
 
There's characters in the scanner input stream that represent Record 
Separators and Group Separators. I can't get the data to scan into a 
single input field on my display file. When the Group Separator character 
comes across, the cursor jumps down a couple lines on the screen. I was 
able to determine this by creating a screen with multiple input fields, 
and then placing the cursor on the top line, and scanning my 2-d barcode. 
Part of the scanned data appeared on the first input field, part on the 
4th line, and then the 7th line. Do I just have to position my input 
fields on the screen in the proper position to capture each piece of 
information coming in? Or what's the proper procedure for capturing the 
scan input for a 2-d barcode. (Especially, since the PDF417 format can 
contain hundreds of characters.)
 
A little background info; I"m on v5r3, and I use TL Ashford software on 
the AS400 to print the barcode label. I'm only printing a small amount of 
data in the barcode. For now, during my testing, I have a part number, 
with AIAG prefix, and a serial number, with AIAG prefix. As a test I 
created a Java program to read the scan input character-by-character. I 
ran the Java program from the PC command prompt. I could see the ASCII 
code 29's and 30's, Group Separators and Record Separators, come across in 
the input. It's the Group Separator character that causes the cursor to 
jump down the screen on the AS400 side.
