No way! I actually find a use for those two now and then. And back when the 41 was new, octal-based machines like the PDP 11 were still fairly common.

I suppose that I am too young, I started with 6502 and it was hex. I never dealt with octal apart from the ancient HP-41 NOMAS list files from HP. Octal is pure pain for me.

Anyway, the point is that there are a couple of dubious instructions that we perhaps could have lived fine without.
