System-Level Command Functions 
 
 
30  Class Series 2 Programmer’s Manual 
 
The sample above produces three labels. The first is formatted 
with the commands between <STX>L and E.  The next two labels 
print with the replacement data contained in the <STX>U 
commands (see <STX>E and <STX>G). The bar code is the same 
length: 3 digits and nine spaces. 
 
 
Truncated Length Replacement Field Functions – A variant of the <STX>U command 
includes the truncate option “T”, where dynamic data shorter than the originally defined 
field length will not
 be padded and the original maximum field length is maintained for 
subsequent replacements.
