使用 xifthen：如何设置 \cnttest 不等于数字

Question

我读过用户手册xifthen包裹。

但是我没有找到“不等于”命令。我该如何设置以下规则：

\ifthenelse \cnttest{\Var} equal A: Do newcommand AAA
\ifthenelse \cnttest{\Var} equal B: Do newcommand BBB
\ifthenelse \cnttest{\Var} equal C: Do newcommand CCC
\ifthenelse \cnttest{\Var} not equal A, AND not equal B, AND not equal C: Do newcommand ABC

其他规则如下：

  \ifthenelse \cnttest{\Var} not equal A, AND not equal B, AND not equal C: Do newcommand ABC

预先感谢

该\ifthenelse宏有三个参数：

\ifthenelse{<test>}{<code for true>}{<code for false>}

因此你可以简单地嵌套调用：

\ifthenelse{\cnttest{\Var}{=}{1}}{Case 1}{%
  \ifthenelse{\cnttest{\Var}{=}{2}}{Case 2}{%
    \ifthenelse{\cnttest{\Var}{=}{3}}{Case 3}{%
       {Case not 1, not 2, not 3}%
    }%
  }%
}
