hm, dunno packages that well -) does this mean that one macro has a whole

well, let me show you a couple of tricks then, see below:

This is text mode anyway, so take your choice:
\def\textfrac#1#2%
{\hbox{\high{\tx#1\kern-.25em}/\low{\kern-.25em\tx#2}}}
test \textfrac{1}{2} test \textfrac{123}{456} test
\def\textfrac#1#2%
{\hbox{\high{\tx#1}\hbox to \zeropoint{\hss/\hss}\low{\tx#2}}}
test \textfrac{1}{2} test \textfrac{123}{456} test
\def\textfrac#1#2%
{\dontleavehmode
\hbox
{\setbox0\hbox{/}%
\setbox2\hbox{\txx57}%
\raise\ht0\hbox{\lower\ht2\hbox{\txx#1}}%
\hbox to \zeropoint{\hss/\hss}%
\lower\dp0\hbox{\raise\dp2\hbox{\txx#2}}}}
test \textfrac{1}{2} test \textfrac{123}{456} test
Now, if you really want to see something nice, say \showmakeup before the
calls to this macro -)
What do others think? Which one is the nicest for default (i opt for the
(as usual best) third one, so that one goes into core-mis.tex and will end
up in the documentation void -)
