The original file of programs (under Mathematica)
for working with 42 equations in 42 variables is
included in its original form "exepac.i.42.s23"
and also in a shortened form that is called
"exepac.42.d.Times.N.R.501.2008.rtf" that was used 
for the display print-out that was used in my presentation
at the ECCAD meeting. 
   Thus the shortened form is prepared for being printed
out but does not include the long formulae for "ff0"
and for "ppvxx".
