See my reply to Werner.  The '.ll' does precede '.TBL' and the line
length is less than the '.ll' length.

Thanks for your work Joachim.  As my first post indicated, I was trying to
do manually what your macro does very well - and I kept making errors.
I wrote a little Python code to generate the groff code which uses
your macro.  Your work made it possible to review dozens of histograms
and statistical analyses very easily.

Regards,

Dean
