NAT _ _ _ _ _ _ _ _ _ _ _ _ switch

When nat is on, output is printed to the screen in natural form, with raised exponents. nat should be turned off when outputting expressions to a file for future input. Default is on.

examples:

(x + y)**3; 

   3      2          2    3
  X  + 3*X *Y + 3*X*Y  + Y  


off nat; 

(x + y)**3; 

  X**3 + 3*X**2*Y + 3*X*Y**2 + Y**3$ 


on fort; 

(x + y)**3; 

  ANS=X**3+3.*X**2*Y+3.*X*Y**2+Y**3

With nat off, a dollar sign is printed at the end of each expression. An output file written with nat off is ready to be read into REDUCE using the command in.
