威綸通漏洞所在？？
macro_command main()
short x=0,y,z
short A[4]={1,2,3,4}
short B[4]={5,6,7,8}

SetData(B[A[0]], "Local HMI", LW, 0, 1)
y=A[0]
SetData(B[y], "Local HMI", LW, 1, 1)

SetData(B[A[x]], "Local HMI", LW, 2, 1)
z=A[x]
SetData(B[z], "Local HMI", LW, 3, 1)

end macro_command

難道是因?yàn)椋珺[A[x]]需要嵌套運(yùn)算三次，比其他的多運(yùn)算一次，所以A[X]沒(méi)有計(jì)算直接按0參與B的計(jì)算了？
