Hi, I tried an example from syst-gen.tex

\def\dosomething#1{(#1=\commalistsize) } \getcommalistsize [\hbox{$a,b,c,d,e,f$}] \dosomething 1 \getcommalistsize [{a,b,c,d,e,f}] \dosomething 1 \getcommalistsize [{a,b,c},d,e,f] \dosomething 4 \getcommalistsize [a,b,{c,d,e},f] \dosomething 4 \getcommalistsize [a{b,c},d,e,f] \dosomething 4 \getcommalistsize [{a,b}c,d,e,f] \dosomething 4 \getcommalistsize [] \dosomething 0 \getcommalistsize [{[}] \dosomething 1

And it gives me

(1=1) (1=6) (4=4) (4=4) (4=4) (4=4) (0=0) (1=1)

Notice that \getcommalistsize[{a,b,c,d,e,f}] gives 6. Is this expected behaviour or a bug?

Looks like a bug to me, unless Hans changed this on purpose?

nice trick: \def\getcommalistsize#1]% don't loose [{#1}] {\commalistcounter\zerocount \processcommalist#1]\p!dogetcommalistsize \edef\commalistsize{\the\commalistcounter}} ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
