Hi,

Here are a few examples of how to use \doifinset and \doifinsetelse (they were given by Wolfgang S. a few years ago…):

\starttext
\type{\doifinset{A}{A,B,C}{should go}:} \doifinset{A}{A,B,C}{should go}

\type{\doifinset{D}{A,B,C}{should go}:}  \doifinset{D}{A,B,C}{should participate}


\type{\doifnotinset{}{A,B,C}{not in the set}:} \doifnotinset{}{A,B,C}{not in the set}

\type{\doifnotinset{D}{A,B,C}{not in the set}:} \doifnotinset{D}{A,B,C}{not in the set}

\doifinsetelse{D}{A,B,C}{it is in the set}{it is not in the set}

\define\test{B}

\type{\doifinsetelse{\test}{A,B,C}{\test\ is in the set}{\test\ is not in the set}}

\doifinsetelse{\test}{A,B,C}{\test\ is in the set}{\test\ is not in the set}
\stoptext


Best regards: OK
