I'm need to input complex pointer like:
[[["REZ.exe"+9A9980]+3*418+1AD08]+4]&0xffffff+[["REZ.exe"+9A9980]+3*418+1AD08]
but I got an error.
Is there work around for that?

Try Lua:
Code:
function myComplexPointerAddr()
  local addr = getAddressSafe'[["REZ.exe"+9A9980]+3*418+1AD08]'
  if not addr then return 0 end

  local offset = readInteger(addr+4)
  if not offset then return 0 end

  return addr + (offset & 0xffffff)
end
Edit: bitwise and (&) has lower precedence than addition (+)
Use "myComplexPointerAddr()" (no quotes) for the address field.

Thanks a lot!
I'm needed to do miner fix though:
Code:
return addr + (offset & 0xffffff)

instead of
Code:
return addr + offset & 0xffffff


Now it's time to learn lua I think.
