REVPRI _ _ _ _ _ _ _ _ _ _ _ _ switch
When the revpri switch is on, terms are printed in reverse order from the normal printing order.
x**5 + x**2 + 18 + sqrt(y); 5 2 SQRT(Y) + X + X + 18 a + b + c + w; A + B + C + W on revpri; x**5 + x**2 + 18 + sqrt(y); 2 5 17 + X + X + SQRT(Y) a + b + c + w; W + C + B + A
Turn revpri on when you want to display a polynomial in a scending rather than descending order.
