The FLIPCOIN.PRG illustrates the use of the RAND() function as presented in Chapter 5. RAND() is a pseudorandom number generator that generates a number between 0.0 and 1.0. In FLIPCOIN.PRG, if RAND() returns a number less than 0.5, a circle with "TAILS" in it displays. Otherwise, it displays a circle with "HEADS" in it. It counts and reports the number of heads and tails as you repeat its operation.
