IBARC, (Version II) Bar Code Command Format

Default Ratio:
Variable Ratio:
When using the IBARC, bar code command format, the type code changes
from a single alphanumeric value to a mnemonic as shown in Table 21. Using
the appropriate alphanumeric command (^M, ^V, ^E, and ^U), IBARC, bar
codes allow you to print bar codes in four orientations: horizontal, or rotated
90, 180 or 270 degrees. In addition, a loc parameter allows you to select one
of three ways in which the printable data field appears below the bar code.
The bar code command parameters applicable to IBARC, bar codes are
defined below. At the end of this section, several IBARC, examples are
provided illustrating applications for these parameters.
NOTE: VGL does not verify that ratio data creates acceptable wide/narrow

type , Represents the IBARC, bar code type from Table
21. Invalid codes are treated as errors.
[R [D] ratio ,] Optional parameter representing the ratios for
variable ratio bar codes. The default ratios shown in
Table 21 are overridden by the variable ratio
feature. Four- and eight-digit ratios can be used,
depending upon the bar code selected. Ratio data
must be decimal values from 0 through 99. Enter R,
followed by the actual bar code ratio. A colon must
separate each element of the ratio.
Like standard bar code ratios, IBARC, ratios are
also interpreted from left to right, measuring the
size of each bar or space, in dot width, in the
following pattern: narrow bar : narrow space : wide
bar : wide space .
If Variable Ratio Bar Code is set to High Resolution
or if the D parameter is specified, the ratios are
represented in actual printer dots instead of line
matrix printer dots (60 x 72 dpi).
element relationships for bar code readability. When designing
unique ratio data, carefully plot wide and narrow ratios to conform to
readable bar codes.
loc
Represents the location of the printable data field.
Enter N for no printable data field, E to have the
data field embedded in the bar code, or B to print
the data field below the bar code. If this parameter
is selected, the printable data field prints in the
current font as selected by the (cc)S or (cc)IFONT
commands or the default font selected.
