We need the example to tell what's wrong -- ie we need HTMLExport as well
as HTMLExport.list.
Based on just this function I can't see why there is a problem or why the
change that you say helps in S-PLUS would do anything.
The question about S-PLUS would be more appropriate for the s-news mailing
list, but if the function called by .C was undocumented in Splus4 it's
quite possible that it doesn't exist in Splus5.
