14. 14 High-level Languages  High-level programming languages Includes third-generation languages Overcame deficiencies of assembly language Programmer didn’t need to manage details of data storage or movement

15. 15 High-level Languages  Expectations of a high-level language program (continued) Programmer can take a macroscopic view of tasks; “primitive operations” can be larger Program will be portable Code will be closer to standard English and use standard mathematical notation
