strange ASM

[callroot]

c0.s="456"

c1.s="789"

!mov [v_c1],[v_c0]


Debug c1

c0.s="456"

c1.s="789"

!mov [v_c1],[v_c0]


Debug c1

callroot should be renamed to spamroot

I agree.

i didnt think you could "mov [mem], [mem]" in the one go (and this is a CPU thing not a PB thing) - you have to "mov reg, [mem]" then "mov [mem], reg". Please correct me if im wrong!

You are not wrong.

Amazing tip btw

Code: Select all

c0.s = " 456 "

c1.s = " 789 "

! mov eax,[v_c0]

! mov [v_c1],eax


debug c1

Code works fine. What's so strange?

Can't write this way.

[wilbert]

! mov [v_c1],[v_c0]


Can't write this way.

That's right and you will never be able to write it this way because asm doesn't support this.

[DontTalkToMe]

There are tables with the possible operands sizes and types you can use with each instruction.

Look there and you'll see you can't move from memory to memory.
