        "Jacobi symbol"
        SYNTAX: X = jacsym(A, B)

        A, B are expressions whose values are integers with the
        following properties:
                - A is an expression whose value is an integer.
                - B is an expression whose value is a positive 
                  odd integer.
                - The values of A and B must be relatively prime.

        X is assigned the Jacobi symbol (A / B).


        Example 1: (correct)

                jacsym(2 * 7 * 11 * 13, 15)


        Example 2: (incorrect)

                jacsym(a1, a2, a3)

        Example 3: (incorrect)

                jacsym(2/3, 15)

_ERR_NR_018


        Example 4: (incorrect)

                jacsym(3, 2)

_ERR_NR_215


        Example 5: (incorrect)

                jacsym(15, 3)
