Code 39 - Full ASCII. Code 39 was developed in 1974 by David Allais and Raymond Stevens, then with Interface Mechanisms Inc. (now Intermec Corporation). Code 39 (Full ASCII) Fonts Morovia Code39 (Full ASCII) Fontware allows you to print Code 39 extended barcode symbols as well as Code 39 symbols from any computer systems. True type, Type 1 for Windows and Macintosh platforms are included in one package and HP PCL versions will be provided upon request - i.e. You can print barcodes from any.
Code 39 is the most popular symbology in the non retail world and is used extensively in manufacturing, military, and health applications. Each Code 39 bar code is framed by a start/stop character represented by an asterisk (.). The Asterisk is reserved for this purpose and may not be used in the body of a message. B-Coder automatically adds the start and stop character to each bar code therefore you should not include them as part of your bar code message. If you select the NORMAL version of CODE 39 and your bar code text contains lower case characters, B-Coder will convert them to upper case. If your bar code message contains any invalid characters, B-Coder will prompt you with a warning message (if the Enable Invalid Warning Messages option is selected in the Preferences menu). Code 39 optionally allows for a (modulo 43) check character in cases where data security is important.
The health care industry has adopted the use of this check character for health care applications. Another feature of Code 39 allows for concatenation of two or more bar codes. It is sometimes advantageous to break long messages into multiple, shorter, symbols. If the first data character of a Code 39 symbol is a space, some readers will store the remainder of the symbol in a buffer and not transmit the data. This operation continues for all successive Code 39 symbols with a leading space, with each message appended to the previous one. When a message without a leading space is read, it is appended to the previously scanned data in the buffer and the entire buffer is transmitted as one long message.
The FULL ASCII version of Code 39 is a modification of the NORMAL (standard) version that can encode the complete 128 ASCII character set (including asterisks). The Full ASCII version is implemented by using the four characters: $/+%. As shift characters to change the meanings of the rest of the characters in the Normal Code 39 character set. Because the Full ASCII version uses shift characters in combination with other standard characters to represent data not in the Normal Code 39 character set, each non-standard character requires twice the width of a standard character in a printed symbol.
Note: Because all of the characters used to implement Full ASCII Code 39 are part of the Normal Code 39 character set, readers that do not support Full ASCII Code 39 will still read Full ASCII Code 39 symbols. The reader will output shifted characters as if they were normal Code 39 characters.

. Code 39 Barcode Symbology Overview Code 39 is a common barcode type used for various labels such as name badges, inventory and industrial applications. The symbology of the Code 39 character set consists of barcode symbols representing numbers 0-9, upper-case letters A-Z, the space character and the following symbols: –.
Lower-case characters may also be easily encoded with the provided in the. The Code 39 barcode is the easiest of the alpha-numeric barcodes to use and is designed for character self-checking, thus eliminating the need for check character calculations. Code 39 is also known as the 3 of 9 Barcode, Code 3 of 9 and Barcode39. Several standards exist that dictate how Code 39 barcodes should be printed for certain implementations. Although a checksum character is optional, many standards require it. The checksum character is a type of provided in many of the IDAutomation for the. Enabling the check digit is also an option within IDAutomation and that allow the component to automatically generate and include the checksum without fonts.
The following standards based on the 3 of 9 barcode require MOD43 check digits:. LOGMARS (Logistics Applications of Automated Marking and Reading Symbols) is a standard based on Code 39 used by the United States Department of Defense. LOGMARS is defined by Military Standard MIL-STD-1189B and others such as MIL-STD-129, MIL-STD-2073-1C and MIL-STD-129N. HIBC is a barcode label used in the health care product industry. Several implementations of HIBC also use. The complete Code 39 barcode consists of a start character, data digits, an optional check character and a stop character.
Start Character Data Digits Optional Check Character Stop Character. CODE-39 P. The Code 39 asterisk character is usually used as a start/stop character, and should not be part of the data in the barcode. The asterisk may be used as the start/stop character with fonts; however, this may cause problems in some applications such as MS Word, because they may treat text surrounded with asterisks as bold text.
In IDAutomation, the exclamation and parentheses characters are also used as start/stop characters to avoid these problems and provide additional functionality. Printing & Generating Code 39 Barcodes Printing of the Code 39 barcode as a font is an easy process if checksum characters are not required for the implementation.
If the checksum is needed, IDAutomation provides several, and for this purpose. IDAutomation Code 39 Barcode Fonts may be created directly from the keyboard or to dynamically produce multiple symbols in many applications, including,.
To create a 3 of 9 barcode manually that encodes the data “BAR CODE-39”, the following may be performed:. Type the start character of “.”. Enter the data to be encoded, which is “BAR CODE-39”. To create the space in the barcode using the standard Code 39 Fonts, an underscore must replace the space in the data to encode: “BARCODE-39”. Type the stop character of “.”. Select only.BARCODE-39.
and change the font to the Code 39 Barcode Font. When the is used, the parenthesis may be used as the start and stop characters to keep the asterisks from appearing in the text interpretation. For example, (BARCODE-39).
2014 Update: IDAutomation now provides that without a substitution character; available in the latest version of the. After installation, these fonts are identified by the “Y” character in the font name, for example IDAutomation YHC39S. Calculated Field Use Code 39 Barcodes may be dynamically created from a calculated field in a text box by using a formula that appends the start and stop characters. This is possible in several applications including the following:. Active Reports: Field1.Text =”.”&Field&”.”. Clarion: loc:barcode=’.’&left(clip(DataField))&’.’.
Crystal Reports: Enter “.” & Field & “.” in a calculated field. FileMaker Pro: Enter “.” & Field & “.” in a so that the asterisk is appended to the beginning and ending of the data from the source field.

When these fonts are not being used, or when it is necessary to encode additional characters, shift functions may be used to extend the character set according to ISO 646.
In order for Extended Code 39 to be decoded properly, the scanner must first be programmed to read it. Otherwise, the scanner will simply scan the existing data, for example “ +C” instead of “ c.” When extended Code 39 is enabled, functions may be directly encoded by using the format $? To specify the function where? Equals the character that represents the appropriate function in the chart below. For example, Code $I 3of9 $M will encode Code TAB 3of9 RETURN.
