I would like to differentiate on the following character being one of X or not X. But cannot get it right in \doifnextcharelse. For example \def\mynextchar{\doifnextcharelse{X}{\def\Next{Y}}{\def\Next{Z}}\Next} delivers: ZX ZQ then input: \mynextchar X \mynextchar Q I hoped for YX ZQ, but it looks as if X tested false against X. How to? Hans van der Meer
