Source Line length Marker or Limit

edit

Hi,

Is there a preference or setting to limit the source line length or to provide some indication of where the end of a source line should be?For example my company's code guidelines regulate the maximum source line length.  No source line can be greater that 100 characters.  I would like to mark the screen or have a setting that stops me from writing after the 100th character on the line.

Thanks,

Neil Shore
