(1) With today's CVS build with gcl, plotting now works. Thanks, Jim.
(2) I still have a problem with putprop & mactex. If I do
(defprop $kummer_m "M" texword)
I get a mess
(%i16) kummer_m(a,b,x);
(%o16) kummer_m(a, b, x)
(%i17) tex(%);
$$\mbox{{}M{}}\left(a,b,x\right)$$
(%o17) false
I still need to do (defprop $kummer_m |m| texword) to get what I want.
It seems that (defprop $kummer_m "M" texword) once worked?
