威纶通case语句

威纶通Case 语句不支持范围的啊，比如1到9，就显示2（语句编译无问题，就是实现不了）
macro_command main()
short a,b
GetData(a, "Local HMI", RW, 0, 1)
select case a
case 0
b=0
break
case 1..9//1到9
b=2
break
case else
b=3
break
end select

SetData(b, "Local HMI", LW, 0, 1)

end macro_command

正确写法
macro_command main()
short a,b
GetData(a, "Local HMI", RW, 0, 1)
select case a
case 0
b=0
break
case 1
case 2
case 3
case 4
case 5
case 6
case 7
case 8
case 9
b=2
break
case else
b=3
break
end select

SetData(b, "Local HMI", LW, 0, 1)

end macro_command

错误实例
macro_command main()
short a,b
GetData(a, "Local HMI", RW, 0, 1)
select case a
case 0
b=0
break
case 1,case 2,case 3,case 4,case 5,case 6,case 7,case 8,case 9
b=2
break
case else
b=3
break
end select

SetData(b, "Local HMI", LW, 0, 1)

end macro_command
