Protect Counters
When the optional Keyboard display unit (KDU) is used, the
label form can be designed to “skip” a consecutive number
prompt, thereby protecting the data. This feature is useful when
the counter represents a serial number or other number that
should not be repeated or changed.
If one (1) minus sign is the first character of the prompt, the
prompt appears only once after the form is retrieved.
Example 1:
C0,10,L+1,“-Enter Serial Number:” 
If two (2) minus signs are the first two characters of the prompt,
the prompt is never displayed.
Example 2:
C0,10,L+1,“- -Enter Serial Number:” 
The protected consecutive number is accessed and modified from
the optional Keyboard display unit only.
To access the protected counter
1 Enter the following when the Keyboard display is showing:
2 (Optional) Press the Exit key to display the above.
3 Press the F1 key.
4 Press 4, 9, 1, and 6.
5 Press the Form key.
6 Key in the form name and press Enter to retrieve.
7 Enter or modify the consecutive number.
8 When complete, print label to store new number in memory.
