Numbering Fields in a Format

About Interpretive Fields and Field Locations

Intermec Printer Language (IPL) Developer's Guide
Defaults for the H0 Field (continued)
Command Definition
Selects the 7x9 standard font.
c0;
Selects no border around human-readable field.
b0;
Selects horizontal orientation of characters.
r0;
You enter variable data in Print mode. The maximum number of
d0,30;
characters you can enter into this field is 30.
This automatically created field is always a human-readable field and is
always assigned field number 0. Because a format must always have at least
one defined field, you cannot delete field 0 if it is the only field in the
format.
To change field 0 to a different type of field (for example, a bar code field),
you have to create a temporary field of any type, delete field 0, create field 0
with a different type, and then delete the temporary field. The next
example shows how this is done:
<STX><ESC>P;E1;F1;L39;D0;B0;D39;<ETX>
The next table describes each command in the string.
Command String Values
Command Definition
Enters Program mode.
<ESC>P;
Erases format 1.
E1;
Creates format 1.
F1;
Creates line field (temporary field).
L39;
Deletes field 0.
D0;
Creates bar code field 0.
B0;
Deletes the temporary line field.
D39;
Be sure you assign a different field number to each field in a format. A
format can have up to 400 fields, numbered 0 to 399.
Keep in mind that you enter data into fields according to their numeric
value if you use a <CR> to separate the data. In other words, the first string
of data you enter goes into the lowest numbered field, the second string of
data you enter goes into the next lowest numbered field, and so on.
Each bar code field can have an interpretive field associated with it. For
example, bar code field B33 would have an interpretive field I33.
