批处理-回声或变量不起作用 [英] Batch - Echo or Variable Not Working

问题描述

我有这个小批处理脚本:

I have this little batch script:

SET @var = "GREG"
ECHO %@var%
PAUSE

当我运行它时，它会打印:

When I run it, it prints:

H:\Dynamics>SET @var = "GREG"

H:\Dynamics>ECHO
ECHO is on.

H:\Dynamics>PAUSE
Press any key to continue . . .

为什么不打印@var的内容?我怎么知道@var是否被设置?

Why won't it print the contents of @var? How do I know if @var is even being set?

推荐答案

请勿使用空格:

SET @var="GREG"
::instead of SET @var = "GREG"
ECHO %@var%
PAUSE
