Windows 为什么CMD会说“为什么”在这个时候是出人意料的”；并在提示中输入内容时关闭？

我最近看了一个VSauce 2的视频，里面有一个你总能赢的游戏，我制作了一个程序，玩家可以和电脑玩这个游戏。问题是，当轮到用户时，当您输入一个数字（或任何内容）时，程序关闭。我和我的一个朋友也试图解决这个问题，但没有任何效果。你能帮忙吗

下面是一段不断出错的代码：

:usr
cls
echo.
echo SUM: %tot%
echo.
echo LAST ENTRY:
echo COMPUTER: %com%
echo YOU: %usr%
echo.
echo.
set/p usr=ENTER A NUMBER BETWEEN 1 AND 10: 
if "%usr%" => "11" (
goto usr
)
if "%usr%" =< "0" (
    goto usr
)
set/a tot=%tot%+%usr%
if "%tot%" == "100" (
    goto win
)
if "%tot%" => "101" (
    goto lose
) else (
    goto com
)

：usr
cls
回声。
回音和：%tot%
回声。
回显最后一项：
回显计算机：%com%
回复您：%usr%
回声。
回声。
set/p usr=输入一个介于1和10之间的数字：
如果“%usr%”=>11(
转到usr
)
如果“%usr%”=<“0”(
转到usr
)
集合/a总计=%tot%+%usr%
如果“%tot%”=100(
后来居上
)
如果“%tot%”=>101(
走投无路
)否则(
转到com
)

每一次转到其他存在的地方

1<代码>usr作为标签和变量的名称 将

usr

用作环境变量的标签和名称不是一个好主意，因为这会使搜索标签或变量

usr

变得困难

不是一回事。Windows批处理文件是一种更痛苦的编程方式。您确定不想使用更好的语言吗？
Gtr
