    一般来说，我写程序都是
    if then
    else
    if then
    end if
    end if

    我可以不可以
    if then
    else
    if then
    end if
    if then
    end if
    if then
    end if
    endif

    这样呢？

    IF THEN END IF
    这组语句用法不是固定的

    如果是

    IF A THEN B

    就不用END IF，有则出错

    如果是

    IF A THEN
    B

    那么下面就要加END IF ，没有则出错

    多层嵌套会出问题的。

    会出什么问题呢？

    如果要进行多重判断该怎么写呢？
