Sometimes I test new versions of Smath with my very old worksheet which keeps failing since 0.98.5973.
This time it puzzled me again. Please see how it performs now.
The SS prints the result of maple(expand(...)) normally,
but after assigning the resulting expression to the variable nnn,
it failed even to display nnn.
What means "Not defined" if it has shown the correct result before?
