SET &TEST_VAR = &TEST_VAR * 5;  /* <-- equals 25 */
SET &TEST_VAR = &TEST_VAR - 10; /* <-- equals 15 */
SET &TEST_VAR = &TEST_VAR / 3;  /* <-- equals 5  */

/* within a function */
CALL SAY(&TEST_VAR + 3);        /* <-- outputs 8 */

In the preceding example, we've used a function call. Discover what functions are in the next chapter.
