Use xifthen: how set \cnttest not equal number

Question

i read user manual of xifthen package.

But i don't find "Not equal" command. How can i set below rule:

\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

And other Rule is below:

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

Thank in advance

Answer 1

The \ifthenelse macro takes three arguments:

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

Thus you can simply nest the calls:

\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}%
    }%
  }%
}
