To remove the BY-group information from the table of contents, modify the ByContentFolder style element. Specify a comment for the style element by using the PRETEXT and POSTTEXT= options. This can be done beginning in Release 8.1. View output.

   proc template;
     define style styles.test;
     parent=styles.default;
       style Bycontentfolder from Bycontentfolder /
             prehtml=_undef_
             pretext='<!--'
             posttext='-->';
     end;
   run;

   proc sort data=sashelp.class out=temp;
     by age;

   goptions device=gif;
   ods html path='c:\test'(url=none)
       body='bod.html'
       contents='cont.html'
       frame='fram.html' style=styles.test;

   proc gplot data=temp nocache;
     plot age*sex / des='#BYVAL(age)';
     by age;
