The document contains two PL/SQL code blocks. The first block declares variables a, b, and c, prompts the user to input values for a and b, sets c equal to b, and outputs which variable is the maximum. The second block declares variables n and sum1, prompts the user for an endvalue, uses a for loop to add odd numbers from 1 to the endvalue to sum1, and outputs the final value of sum1.
