I actually had small bits of code, sorta like a prefix and a suffix, that delimited the data scanned so that when the FoxBase+ app (later FP1) read in the data, it had something to parse. Hey, it wasn't pretty, and there was no subclassing going on, but it worked. I was concerned mainly that the user would not always put the data in in the order the programmer intended. <g> Code 39 is what I used. I was even able to setup a paper menu that contained carriage returns, and Page Downs (yeah, page downs to get you all the way through a READ). I had some hand held units, one from Intermec, and some from CMT (Corvallis MicroTechnology, I think). The one from Intermec had its own proprietary language called Interactive Reader Language or IRL for short. They used to call me the Duke of IRL when I worked with what seemed like programming in an EDLINesque language. The CMT units actually had a version of dBase on board and had a bigger screen (or is that form). Anyhow, just my two cents... ==Carl
