Remarks
For example, in CPCL, the following format will contain 2 FieldDescriptionData.
            ! DF SHELF.FMT
            ! 0 200 200 210 1
            CENTER
            TEXT 4 3 0 15 \\
            TEXT 4 0 0 95 \\
            FORM
            PRINT
            
The first FieldDescriptionData will contain a fieldNumber of 1, and a fieldName of null. The second FieldDescriptionData will contain a fieldNumber of 2, and a fieldName of null.


In ZPL, the following ^FN command will contain 2 FieldDescriptionData.
            ^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 FieldDescriptionData will contain a fieldNumber of 15, and a fieldName of "Address". The second FieldDescriptionData 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 FieldName 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.
