Assembly controller programming

Question

See more: (untagged)

My code is:

ASM

org 0
    mov a,r0
    mov r0,a
    mov r1,a
    mov r2,a
end

"a" - accumulator
"r0 - r2" - internal memory registers

I'm using asm51 compiler, and load .hex file in fd51.exe

Is it possible to put 3-rd,4-th and 5-th rows into one, something like "mov (r0,r1,r2),a"?

Let imagine that you can...What do you expect that kind of command will do? Set all of r0, r1 and r2 to a?

Let me tell you: there are many controllers in the worlds, not just one; same goes about the languages and architectures (instruction sets). How can we know what you are talking about?

Yes you can just use :

ASM

org 0
    mov a,r0
    mov r2,a
end

Since the instructions in between are redundant, and have no effect.

You should be aware that most of programming is like mathematics and there are only two sides to an equation/operation, and if you don't do something useful in between you can factor the middle operations out.
