Dear sirs,
I need some clarification. Kindly help me.
For example:
\def\kk{lllll}
\def\aa#1{\edef\kk{\kk#1,}}
\aa{aa}
\aa{bb}
\aa{cc}
\aa{dd}
\kk===>output is ``llll,aa,bb,cc,dd,''
I wish to remove the last comma; the out put must be ``llll,aa,bb,cc,dd''
The input of \aa repeated several times (not fixed times). We could not
modify the input ``\aa''. How to remove the
last puncutation , or add new punctuation in last position.
Regards
