Sigh. Autocorrect on my phone strikes again-should say 28th line.

We had an option on NitrOS9 builds to enable the 225 scanlines on 80x25 (which added a blank scanline between each text line, giving better separation between characters vertically, making it much easier to read), but you pretty well needed an RGB monitor to see it properly. TV owners told us to put it back to 200 scanlines again; so we made it a flag at assembly time to let us generate both versions. (hmmm ... I think I will add this to the upcoming SS.GIP2 call so that one can change it on the fly).
