Bar Code Command Format

Bar code commands are Extended Graphics commands which must occur

within the Graphics Mode and must be introduced by an SFCC and one of the

four alphanumeric commands (^M, ^V, ^E, and ^U). Data provided in the

alphanumeric command sequence identifies specific height, width, and

justification information used to define bar code length (height) and position.

Complete alphanumeric command information is explained in the

“Commands” chapter.

Throughout this manual, the caret (^) is used to represent the Special

Function Control Code introducer and terminator for graphics and bar code

commands. Be sure to use the appropriate control character for your Code V

configuration.

Code V offers a choice between two types of bar code command formats

which are described on the following pages: Standard (^B and ^C) bar code

format, and IBARC, (a QMS Version II command). Neither format offers

significantly more or less features; both formats will accomplish the same

task. The format you select is a matter of personal choice. In each bar code

section throughout this chapter, each of the command parameters is fully

described and examples provided using the standard bar code format (^B and

^C) .

When using variable ratio bar code commands, you must ensure the

“scanability” of your bar codes. Make sure the variable ratio conforms to the

specification.

The bar code command and associated parameters for standard bar codes

are described on page 134. IBARC, bar codes, associated parameters and

examples are described on page 135.

Each bar code parameter is visually separated by spaces, and optional

parameters are marked by paired brackets [ ];

do not enter these spaces or

brackets

in your command sequence; they are provided throughout the

manual for clarity in distinguishing parameters. Italicized text represents a

variable parameter for which a value must be inserted. Command parameters

not italicized must be input exactly as shown.
