I. Course Prefix/Number: CIS 123
Course Name: Introduction to Cobol Programming
Credits: 4 (3 lecture; 2 lab)
III. Course (Catalog) Description
IV. Learning Objectives
- Report listings with headings and totals
- Multilevel total reports
- Single and multilevel tables - using subscripting
- Elementary multi-file input reports
The student will be able to process data using both unit record and mass storage devices. In addition he/she will be able to explain:
- The functions and purpose of all the divisions of a COBOL program.
- The different types of internal data representation and the advantage of each.
- The relationships of symbolic device assignments within the COBOL program to the operating system being used.
Finally, (s)he will be able to debug problem programs with the aid of the COBOL debugging tools, and prepare complete, comprehensible documentation.
V. Academic Integrity
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.
There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.
Details of the Code of Academic Conduct can be found in the Student Handbook.
