Barcode scanning
DDS, DSPF, Barcode scanners
We develop and use a lot of barcode scanning and reading applications. Some of the portable scanners in the warehouse allow the user to establish a session to the AS400 via a wireless bridge. Once signed on, the user is presented with the scanning application. Due to the fact that their scanners screen is 1/6 of the actual screen (meaning they have scroll bars top and bottom to shift the screen to the area they desire) I tried to modify the application screen to fit in this small area. The scan field is 240 bytes wide which wraps around the screen several times. I tried to use the DDS keyword CNTFLD with a column width of 024, which fits nicely in the 1/6 of the screen without scrolling. The problem is when attmpting to scan, I receive an error message stating that the field is too small to receive the value. If I remove the keyword, it scans fine. Why is this?
Is there something I'm missing?
