The document contains 15 programs demonstrating the use of PL/SQL blocks, functions, and cursors. Program 1 finds the maximum of 3 numbers. Program 2 calculates the sum of the first 100 natural numbers. Program 3 calculates the sum of the first 100 even and odd numbers separately. The remaining programs demonstrate additional PL/SQL concepts like cursors, functions, implicit cursors, table creation and manipulation.
