第一次用威纶通的HMI,想在屏上显示程序行号，当LW=0，时在屏上的LB0=1，显示为红色，然后，当LW=1时，LB1=1,LB0变为0，也就是说，LW=n,LBN=1，共300行，写了一段宏代码，能用，但是，300行那么多，有没有更简的方法吗？希望高人指正，谢谢。
下面是宏代码：限于篇幅只列出0到4步
macro_command main()
short a
bool on=1,off=0
GetData(a,"Local HMI",lw,0,1)
if a==0 then
SetData(on,"Local HMI",lb,0,1)
else
SetData(off,"Local HMI",lb,0,1)
end if
if a==1 then
SetData(on,"Local HMI",lb,1,1)
else
SetData(off,"Local HMI",lb,1,1)
end if
if a==2 then
SetData(on,"Local HMI",lb,2,1)
else
SetData(off,"Local HMI",lb,2,1)
end if
if a==3 then
SetData(on,"Local HMI",lb,3,1)
else
SetData(off,"Local HMI",lb,3,1)
end if
if a==4 then
SetData(on,"Local HMI",lb,4,1)
else
SetData(off,"Local HMI",lb,4,1)
end if

end macro_command

循环就行啦啦啦啦

macro_command main()
unsigned  short i
bool on=1,off=0,a[100]
GetData(i, "Local HMI", RW, 0, 1)
FILL(a[0],0,100)
SetData(a[0], "Local HMI", LB, 0, 100)
SetData(on, "Local HMI", LB, i, 1)
end macro_command

谢谢高手指教，的确很简，学到东西啦！！
