bat - ECHO 在 txt 文件中关闭
:obje7
set gn=%random%
if /i %gn% lss 1 goto obje%go%
if /i %gn% gtr 5 goto obje%go%
set goal%gn%="test"
echo hi > goal%go%.txt
echo hi > g2.txt
goto go
在 goal%random_number% 中设置测试，对吧？
(
echo %goal1%
echo %goal2%
echo %goal3%
echo %goal4%
echo %goal5%
) >> mcbingo.txt
我得到的结果是：
ECHO is off.
test
ECHO is off.
test
test
并且所有 :objeX 都是相同的代码，但更改了 X 并且 g2.txt 是 g1.txt 例如。
有人知道出了什么问题吗？

set goal%gn%="test"
echo hi > goal%go%.txt
echo hi > g2.txt
goto go
that sets test in goal%random_number%, right?
(
echo %goal1%
echo %goal2%
echo %goal3%
echo %goal4%
echo %goal5%
) >> mcbingo.txt
and the result i get is:
ECHO is off.
test
ECHO is off.
test
test
and all the :objeX are the same code, but changed X and the g2.txt is g1.txt for example.
anyone have any idea whats wrong?

您的一些
目标变量仍未初始化。当您输出它们时，未初始化的变量计算为空字符串，相应的 echo 命令看起来像这样：如果没有参数，echo 显示回显批处理命令的状态控制台（当
ON时，它们会显示，当OFF时，这在批处理中更常见，但它们不显示）。要避免此行为并显示空字符串，请在
echo和%goal...%之间添加分隔符。您可以在该位置使用许多分隔符，但是，如下所示 这个答案，(似乎最合适：Some of your
goalvariables remain uninitialised. When you are outputting them, the uninitialised variables evaluate to empty strings, and the correspondingechocommands simply look like this:Without parameters,
echodisplays the status of echoing batch commands to the console (whenON, they are displayed, whenOFF, which is more typical in batches, they aren't).To avoid this behaviour and display empty strings instead, add delimiters between
echos and%goal…%s. There's a number of delimiters you can use in that position, but, as follows from this answer,(seems most appropriate:
