No in a real macro, here is a problem I posted a long time ago where
I was now able to replace my low level catcodes changes with catcode
tables, I hope this will help other users if they have the same problem.
\unprotect
\newcatcodetable \diacatcodes
\startcatcodetable \diacatcodes
\catcode`\^^M = 5
\catcode`\ = 10
\catcode`\\ = 0
\catcode`\{ = 1
\catcode`\} = 2
\catcode`\% = 11
\catcode`\! = 11
\catcode`\? = 11
\stopcatcodetable
\def\????ax{@@@@ax}
\def\setupaxis
{\pushcatcodetable
\setcatcodetable\diacatcodes
\dodoubleargument\dosetupaxis}
\def\dosetupaxis[#1][#2]%
{\def\docommand##1{\getparameters[\????ax##1][#2]}%
\popcatcodetable
\processcommalist[#1]\docommand}
\setupaxis
[\c!x,\c!y]
[\c!format=%d]
\protect
\starttext
\getvalue{@@@@axxformat}
\stoptext
