What is the purpose of the Randomize() function?

The purpose of the Randomize() function is to initialize the Rnd() function so that it generates different random numbers each time the program is executed. By seeding the random number generator with a unique value, often based on the current time or system state, Randomize() ensures that the sequence of random numbers produced is not the same across different runs of the program. This is crucial for applications that require varied outcomes, such as games or simulations, where duplicate sequences could undermine the intended randomness and user experience.

In contrast, generating a constant random number or creating predictable sequences would defeat the purpose of using random numbers for tasks like simulations, cryptographic applications, or any scenario where unpredictability is essential. Clearing previously generated random numbers is not the role of Randomize()—instead, it is about initialization to foster variability in future calls of Rnd().
