Characters can be enabled via the menu (see the Operator’s Manual for additional 
information).

STX U  Label Format String Replacement Field 
 
This command places new label data into format fields to build a label. Two options are 
available: Exact Length and Truncated Length.  
 
To easily keep track of fields, place all of the fields to be updated with the command at 
the beginning of the label format. A maximum of 99 format fields can be updated. Fields 
are numbered consecutively 01 to 99 in the order received. 
 
Exact Length Replacement Field Functions – The new data string must equal the 
original string length and contain valid data. When the dynamic data is shorter than the 
length of the originally defined data field, then field will be padded with blanks (or zero 
when the Format Record header specifies a numeric bar code).
