Re: preventing lines from printing with substitution tables

[Harry Binswanger hb@xxxxxxxx]

If you wrap the line in ≪NT...≫ or ≪IV...≫ it won't print. The
difference is that with NT you see a delta onscreen, with IV (InVisible)
you don't. You may or may not wanted to include the CR-LF in what's
non-printing.
