+### maxDataLineLength
+
+Datalines can be very wide, so to avoid the need to increase `maxLineLength` for the entire project, it is possible to raise the line length limit for the data records only. On a related note, as a developer, you should also be aware that code submitted in batch may have a default line length limit which is lower than you expect.  See this [usage note](https://support.sas.com/kb/15/883.html) (and thanks to [sasutils for reminding us](https://github.com/sasjs/lint/issues/47#issuecomment-1064340104)).

+The `maxDataLineLength` setting is always the _higher_ of `maxDataLineLength` and `maxLineLength` (if you set a lower number, it is ignored).

 ### maxHeaderLineLength
 
 In a program header it can be necessary to insert items such as URLs or markdown tables, that cannot be split over multiple lines.  To avoid the need to increase `maxLineLength` for the entire project, it is possible to raise the line length limit for the header section only.
