A semicolon or dollar sign can be added at this point to execute the statement. In interactive mode, a statement that ends with a dollar sign <em>$</em> and a <em>Return</em> is executed, but the results not printed. <P> <P> Inside a <A HREF=r37_0038.html>group</A> statement <em><<</em>...<em>>></em> or a <em>begin</em>...<em>end</em> <A HREF=r37_0041.html>block</A>, a semicolon or dollar sign separates individual REDUCE statements. Since results are not printed from a <A HREF=r37_0041.html>block</A> without a specific <A HREF=r37_0058.html>return</A><P> <P> statement, there is no difference between using the semicolon or dollar sign. <P> <P> 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. <P> <P> <P> <P>
