TriCoder keypad and enter the new value.
The MAX DATA LEN is important when using the Xtra Statement. See
the section on the XTRA STATEMENT for more information.
• Minimum Data Length
The MIN DATA LEN field tells the TriCoder the fewest number of
characters to accept for a particular program statement. Specifying a
Minimum Data Length can reduce data entry errors and is particularly
important when using an Xtra Statement. The Minimum Data Length
should take into consideration Data Identifiers if your data uses them.
