Barcode types supported

In the table below the types of barcodes supported by this release of the library are summarised, together with the type and number of characters, which are specified for that barcode type. In this connection "any" means capital letter and number characters; in some cases additional characters are defined, but lower case letters are not permitted.  The code# represents the code type number used in calls to the dBarcode DLL (DLSBAR32.DLL).

Telepen provides codes for upper and lower case letters and most printable characters. Only Extended Code 39 and the EAN 128 and Code 128 codes provide symbols for the full ASCII character set.

There are many named barcode types, which are actually derivatives of major types. To avoid the table (and user-programming) becoming excessively complex, both the table and calls to the library report only the generic name.

For example: The ISBN, ISSN and JAN coding scheme are all variants of the EAN scheme.

There are several coding schemes (such as DEFCON) which are actually Code 39, and some countries use Code 128 under other names for mail tracking (as in the UK).
