\func{}{wxCONCAT4}{\param{}{x1}, \param{}{x2}, \param{}{x3}, \param{}{x4}}
\func{}{wxCONCAT5}{\param{}{x1}, \param{}{x2}, \param{}{x3}, \param{}{x4}, \param{}{x5}}
These macro return the concatenation of the tokens passed as their arguments.
Unlike when using the preprocessor \texttt{##} operator, the arguments undergo
the macro expansion before being concatenated.
