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.
