Subset A supports numbers, upper-case letters, and control characters, such as tab and new-line.

Subset C supports numbers only

 

BarCodeWiz ActiveX Specific

•

Check characters are computed automatically.  You do not need to enter nor compute them.

•

Use Code 128 Auto whenever possible.  This setting will encode your data with the shortest possible number of bars.

•

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).
