Enter the data for the bar code. A null data field (no
characters) is permitted. The length of the data field is
variable; however, the maximum length is usually
limited to 32 characters to minimize potential reading
errors.
Optional parameter to enable printing of the human
readable data field. Enter PDF to print the data field. If
the parameter is not used, the human readable data will
not print. This parameter is not allowed if a null data
field was specified.
LOC
Optional parameter to identify the location of the
printable data field. The default value is B, locating the
human readable data below the bar code. A locates the
printable data field above bar code. To compensate for
printing the 0.1–inch high data, the height of the bar
code body is reduced 0.1 inch.
FONT
Optional parameter to select the font for the human
readable data field. The default value, N, selects the
normal ASCII 10 cpi font. Enter O to select the
OCR–A 10 cpi font; enter X to select the OCR–B 10
cpi type font.
STOP
Ends the Bar Code command while the IGP/PGL
continues in the Create Form Mode. Enter STOP. If
STOP is not entered, an error message results.
