[comp.text.tex] LaTeX macros needed for superscript-style citation

jiang@hbar.rice.edu (Jun Jiang) (06/15/90)

The LaTeX \cite{a,b,c,d} will generate TEXT [1,2,3,4].  I would like
to have a superscript-style citation \citem.  Its output should look
like the following if one calls \citem{a,b,c,d}:

                1--4 
    ...... TEXT,     ....... 

Does anyone outthere know how to do this?
