This code defines a function named CHECKPRIME that takes an integer parameter X. It then checks if the input number X is a prime number by iterating from 2 to X-1 and checking if X is divisible by any number in that range. If X is divisible by any number, the function returns FALSE, indicating that X is not a prime number. If no number in the range divides X, the function returns TRUE, indicating that X is a prime number.
