Code 39 and Code 39 Extended
|
|
 
Code 39 is the most popular non-retail symbology. It supports numbers, upper-case letters, and several special characters.
Code 39 Extended supports all ASCII 128 characters by using double character encoding. For example, the lower-case letter "a" is represented by "+A". Because of the possibility of misrepresentation of a symbol, most bar code scanners need to be switched to extended mode in order to recognize Code 39 Extended.
BarCodeWiz ActiveX Specific
| · | The start and stop characters (represented by the asterisk character *) are added automatically if needed.
|
| · | The check character can be added to the bar code and/or text by setting the OptionalCheckChar property to Barcode_Only or Barcode_And_Text.
|
| · | In Code 39 Extended, control characters, such as TAB or NEW LINE, may be encoded by entering their three digit ASCII code prefixed by a caret (^).
|
| For instance, "1234^009" will encode "1234" followed by a tab character (ASCII 009).
