The start code and subset switching is done
automatically by IGP based on the data field
contents so that the bar code length is minimized.
Subset C encodes each pair of numbers as a single
bar code character, providing a higher character
density. If the first four data digits are numbers, the
bar code starts in subset C; otherwise it starts in
subset B. The subset will switch from B to C at any
point in the data field if the next four characters are
numbers, and will switch from C to B if the next two
characters are not numbers or only one character
remains.
The data field can contain any of the characters
listed in Table 13 except the system SFCC and the
character used as a delimiter.
PDF Optional parameter to enable printing of the human
readable data field. Enter PDF to print the data
field. If this 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 the bar code.
The height of the bar code body is reduced to
compensate for the human readable field and the
guard bands.
FONT
Optional parameter to identify the font of the
printable data field. Enter O to select OCR-A font;
enter X to select OCR-B font; enter N to select 10
cpi; enter P to select 12 cpi; enter Q to select 13
cpi; enter R to select 15 cpi; enter T to select 17 cpi;
enter V to select 20 cpi.
STOP Ends the bar code command while the IGP
continues in the Create Form mode. Enter STOP. If
STOP is not encountered, an error message
results.
