Hello all,
As noted by Enrico Gregorio
(http://chat.stackexchange.com/transcript/message/28883985#28883985),
the behaviour of \mathstyle seems to be odd:
$\scriptstyle\count255=\mathstyle 3 \the\count255$\par
$\scriptstyle\count255=\scriptstyle 3 \the\count255$\bye
Unlike similar variables, \mathstyle is not terminated correctly. I also
see that \(show)the\mathstyle is an error rather than what one might
expect here.
The manual doesn't specify, but I assume this is not deliberate?
the manual specifies that it's a convert command (and readonly) so it
just injects a sequence of tokens
you can use
\numexpr\mathstyle\relax
if you want to terminate
