下面有一些代码，旨在帮助将choco包自动安装到repo上。
然而，我得到的不是执行命令(正确地回显)，而是从数字1开始的一系列数字。
如有任何建议，我们将不胜感激！
参考代码：
@echo off
set arr[0]=sts
set arr[1]=winscp
set arr[2]=tortoisegit
set arr[3]=office2013pro
set arr[4]=notepadplusplusandpm
set arr[5]=git
set arr[6]=GoogleChrome
set arr[7]=jdk
set arr[8]=maven
set "x=0"
:SymLoop
if defined arr[%x%] (
call set entry=%%arr[%x%]%%
set command=choco install %entry% -y
REM Command isn't running, just prints off numbers
%command%
set /a "x+=1"
GOTO :SymLoop
)
输出如下：
123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767777980818288586878909192939596979899100101102103104105106107108110111112113114115117118119120121122123124125127128129130131133134135136138140141142143144145146148149150151152153155156158159160161162163164165166167168169170171172173174175177178179180181182183184185186187188189191192193194196197198199200201203204205207208209210211212213214215216217218220221222223224225226227228230231232233235237239240241242244246247248250251252253254255256258260261262264266267268269270273274275277279280281282283284286288290292294295296297298299300301302303305306307308310311312313314315316317318320321322323324325327328329330331332

更改2行，就可以避免使用括号中的代码块。
这有助于避免延迟扩张的需要。需要延迟扩展的示例如set /?所示。
set VAR=before if "%VAR%" == "before" ( set VAR=after if "%VAR%" == "after" @echo If you see this, it worked )
括号之间的所有内容都读取为1个块，并计算一次。因此，括号内的%VAR%不会改变，因为它已经被该值替换。
