Reading a bar code

I've got a 15 character field into which I'm reading a bar code. The data can contain as few as six characters or as many as 15. I want the program to receive an ENTER after the scanner reads the bar code (regardless of the number of characters. (I'm using RPG/LE).

With most RF vendors, you can set a parameter in the RF that will do an auto enter if the barcode field is less than the full length. If your barcode allows spaces (like a three of nine) you could also barcode-trailing spaces and make your field auto enter in your program. I would favor changing it in the RF.
