Field, Select  
Purpose  To choose a data field for data entry.
Syntax  
<ESC>Fn
Supported  
Based on testing, this command works the same on the Zebra printer with 
APL-I firmware as on the 3400D printer.
Notes  
You must set the parameter for this command to the field number or the field name.
Things to be aware of:
If you do not set the 3parameter, the printer defaults it to 0.
If you choose the field number, the printer enters data into field n.
If you enter a field name, the printer enters the data into a field with a particular name. 
You must enclose the field name in quotation marks. 
Entering an invalid field code generates error code 38.
Field Decrement, Set  
Purpose  To set the field decrement value.
