Reading is real easy using a wand or other reader that gets connected between your keyboard and computer (be it on a PC or a terminal). Any input from the reader is simply like input from the keyboard and is allways in ascii so it can be read with a standard input statement in 4GL or equivalent in other languages. Most readers can be set up to generate special codes before and/or after the actual bar code data so you can trap the data and put it into the right field using on key in 4gl or similar features in other languages. It's another matter if you want to read bar codes off an assembly line or in other similar situations where you may get a stream of bar code and possibly other data.
