[cctalk] RSX11M (not PLUS) v4.8 question

So, I may just be spoiled from using RSX11M-PLUS and now expect too much from the RSX11M OS. But it seems to me the CLS command would be a nice-to-have, but I am not able to find anything about it. So did that not exist for RSX11M? How does one clear the screen in that environment? -Peter
