For example, in CPCL, the following format will contain 2 .
! DF SHELF.FMT
! 0 200 200 210 1
CENTER
TEXT 4 3 0 15 \\
TEXT 4 0 0 95 \\
FORM
PRINT
The first will contain a fieldNumber of 1, and a fieldName of
null. The second will contain a fieldNumber of 2, and a fieldName of null.
In ZPL, the following ^FN command will contain 2 .
^XA
^DFR:SHELF.ZPL^FS
^FO25,25^A0N,50,50^FN15"Name"^FS
^FO25,75^A0N,50,50^FN15"Address"^FS
^FO25,125^A0N,50,50^FN18^FS
^FO25,175^A0N,50,50^FN15
^XZ
The first will contain a fieldNumber of 15, and a fieldName of
"Address". The second will contain a fieldNumber of 18, and a fieldName of null.
Note: If a label format contains multiple Field Numbers, only 1 will be returned since the data will be shared
by all variables with the number. The portion of the variable will be the
last one in the format, unless it is not present.For example, in the format above, there are 3 ^FN15's. The
first 2 have a "prompt" parameter, the third does not. The second one, "Address", overwrites the first one, "Name".
The third one is not present, so the previous one, "Address", is preserved.
