; _ _ _ SEMICOLON _ _ _ _ _ _ _ _ _ _ _ _ command

The semicolon is a statement delimiter, indicating results are to be printed when used in interactive mode.

examples:

(x+1)**2; 

   2
  X  + 2*X + 1 


df(x**2 + 1,x); 

  2*X

Entering a Return without a semicolon or dollar sign resu lts in a prompt on the following line. A semicolon or dollar sign can be added at this point to execute the statement. In interactive mode, a statement that is ended with a semicolon and Return has its results printed on the screen.

Inside a group statement <<...>> or a begin...end block, a semicolon or dollar sign separates individual REDUCE statements. Since results are not printed from a block without a specific return statement, there is no difference between using the semicolon or dollar sign. In a group statement, the last value produced is the value returned by the group statement. Thus, if a semicolon or dollar sign is placed between the last statement and the ending brackets, the group statement returns the value 0 or nil, rather than the value of the last statement.
