         B.1.17 Compound Statements
         
         Suppose we need to do more than one thing depending on the value of a predicate. If we need to execute 
         multiple statements that depend upon a common predicate, we can group them together into a list of 
         statements. For example, {m = n; n = r;} is a list of statements, also called a compound state-
         ment. Consider steps 2 and 3 of Euclid's method (see section 9.2.2), which can be expressed:
         *****************************************************************************/
        
        Integer m, n = 1, r = 1;
        
        If (r == 0)
                Halt(n);
        Else {
                m = n;
                n = r;
        }
        
        /*****************************************************************************
         If r is not equal to 0, first m is assigned the value of n, and then n is assigned the value of r. We 
         express this in Musimat by making these two steps into a compound statement.
         
         Any legal statement can appear within a compound statement, including other compound state-
         ments. This means we can nest compound statements inside each other.
