Overview

Code 93 is a discrete, variable length, self-checking symbology that is discrete, variable length, and self-checking. The basic character set is the same as Code 39 but the symbols have a higher density. Extended code 93 can encode full 128 character ASCII using four additional shift characters.

Invoking

• The data field can hold any of the following:

  • Numbers 0-9
  • Capital letters A-Z
  • Symbols -.$/+%* and <space>
  • In the extended symbology, the shift characters accessed by ^043 to ^046.
• The includecheck option calculates the two mod 47 check digits

Example Code 93

0 0 moveto (TERRY BURTON) (includecheck) code93 barcode

Example Code 93 Extended

Unlike with Code 39 Extended, which doubles up the meaning of the Code 39 characters $ / + % to provide a set of shift characters, Code 93 Extended instead provides a set of special shift characters, sometimes written as ($) (/) (+) (%), who's codes are distinct from their basic Code 93 counterparts. The ordinal values for these characters are 43, 44, 45 and 46 respectively and can encoded in the same way as for non-printable characters in the other encoders, e.g. ^043, ^044, etc.

To encode "Terri<BS>y" where <BS> represents a backspace in Code 93 Extended:

0 0 moveto (T^046E^046R^046R^046I^043H^046Y) (includecheck) code93 barcode
