Yeah, if it goes completely nuclear and clears the registers, stack, and resets the program counter and halts, then I definitely can't see any good use for it inside a program. But then one wonders why the command is labeled "CLR REG"; maybe a little picture of a frustrated accountant sweeping everything off the desk into the trash would be a better choice.

Doesn't the 41C Extended Functions have something similar? Or am I just thinking of the "copy a block of registers" command? In any case, you could implement it in just a few steps with ISG.
