最满意答案

你可以做and嵌套的条件：

if %age% geq 2 ( if %age% leq 12 ( set class=child ) )

要么：

if %age% geq 2 if %age% leq 12 set class=child

您可以使用or使用单独的变量：

set res=F if %hour% leq 6 set res=T if %hour% geq 22 set res=T if "%res%"=="T" ( set state=asleep )

You can do and with nested conditions:

if %age% geq 2 ( if %age% leq 12 ( set class=child ) )

or:

if %age% geq 2 if %age% leq 12 set class=child

You can do or with a separate variable:

set res=F if %hour% leq 6 set res=T if %hour% geq 22 set res=T if "%res%"=="T" ( set state=asleep )
