### lowerCaseFileNames
On *nix systems, it is imperative that autocall macros are in lowercase. When sharing code between windows and *nix systems, the difference in case sensitivity can also be a cause of lost developer time. For this reason, we recommend that sas filenames are always lowercase.

### 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)).

## Upcoming Linting Rules:
- `noGremlins` -> identifies all invisible characters, other than spaces / tabs / line endings. If you really need that bell character, use a hex literal!
- `lineEndings` -> set a standard line ending, such as LF or CRLF
