好的，所以我有这个小游戏，我正在这台Windows XP计算机上批量编写。当我运行以下代码时，我得到“此时没有预料到”（对不起，它真的很长，我还没有把它缩小。注意我没有要求你让我代码较小，所以请不要这样做）：

    @echo off 
    set str=0
    set int=0
    set agi=0
    set dex=0
    goto chrselect

    :chrselect

    echo 3) archer
    set /p start=-

    if %start%==3 goto battleattk
    goto battle2

任何时候我进入：战斗屏幕并按下我预设的选项，此时不会被预料到。

当您到达%blockrandm%时，您的变量:battle2未初始化，因此第148行的比较显示

if ==0 set bossd=0

这显然是无效的语法。您可以通过引用比较的两面来避免它（在编写此类代码时几乎在所有情况下都是伟大的想法）。

供将来参考：删除echo off并至少看看哪条线是负责的，通常也是为什么它失败。

这个时候没有预料到批次？
