# Is there a \show for catcodes?

In the course of attempting to out-pedant another mathematician, I wanted to \show the catcode of \$ to convince myself that it was a "special" character in ordinary TeX as well as LaTeX. I was just using a "dumb tex" session (that is, I invoked tex from the commandline with no file) so what I wanted was to be able to type:

\showcatcode\$

but that didn't work. In the end, I did

\count255=\catcode`\$
\showthe\count255

but that just doesn't smell right. What's the best way to \show the catcode of a token?

(To be clear, the result of a \showcatcode should go to the terminal and the log, not in the document itself.)

I believe that \showthe works for any internal integer, even strange ones like \parshape. –  TH. Jun 9 '11 at 12:19
