Talk:Code 39

From Wikipedia, the free encyclopedia

I think I have noticed a thin white space (Format 2: 'w') between each character in this barcode fromat. Is this worth mentioning in the article?--Commander Keane 11:02, 11 Feb 2005 (UTC)

That space is definately there. That's why Code 39 is a 'discrete' code, rather than a 'continuous' code (eg, Code 128). It's probably worth mentioning, but then there's a bunch of other things worth mentioning too. Are we trying to put the full specification of Code 39 here? :) Personally, I think that would be cool :) -- Ch'marr 19:14, 15 March 2006 (UTC)

I added a link to a specification page in another Wiki. Up to now, however, this seems to include less information than this Wikipedia article. wr 87.139.81.19 13:25, 31 October 2007 (UTC)

[edit] A better way of representing the code.

Personally, I dislike the 'NwN' and 'bWb' nomenclature for representing the code. There's too much of a 'disconnect' between this nomenclature and how it's represented in real life (as black and white regions). Does anyone else do it this way? Ideally we should be using graphics, but I can certainly understand that that isn't feasible here. Instead, I propose using '#' and '_' characters to represent a dark and light region. For example, use this for the letter L:

#_###_#_#___###

. This would also be useable for the other barcoding standards. -- Ch'marr 19:19, 15 March 2006 (UTC)

[edit] External Links

This section needs to be pruned. There are far too many links providing too little information. Most of them are not much more than thinly veiled links to commercial software. --Millbrooky 16:09, 24 October 2006 (UTC)

Please refer to the Talk:European Article Number page for further discussion. --Millbrooky 16:53, 24 October 2006 (UTC)

[edit] Code 39 Extension

Does anyone know of the US Code 39 Extension coding? If so, please post its specifications. Thanks. 75.31.138.94 19:12, 7 January 2007 (UTC)
