The following programs demonstrate the use of the MAX function in
    an assignment statement. These programs:
    o  Declare a host variable, latest_degree
    o  Use the MAX function to compute the highest number stored in
       YEAR_GIVEN in the DEGREES relation
    o  Assign this computed value to the host variable
    o  Print an informational message and the value computed by the
       MAX function
