Hello, \catcode`\{=1 \catcode`\}=2 \def\msg{\immediate\write16 } \mathchardef\foo=-1 \msg{[\the\foo] [\meaning\foo]} \csname @@end\endcsname\end Result with different values: [-1] [\mathchar"000/] [-2] [\mathchar"000.] [-3] [\mathchar"000-] [-16] [\mathchar"00/0] [-256] [\mathchar"0/00] ... Similar behaves \omathchardef. The documentation says, the valid ranges are \mathchardef: 0--"8000 \omathchardef: 0--"8000000 Thus it's probably a bug that negative values are accepted. Yours sincerely Heiko Oberdiek
