Subject Title
Business Application Using RPG

Subject Description
This subject is oriented towards business application programming on the IBM AS/400. Students will design, code and test programs using modular techniques. Programming assignments include control breaks, sequential and random processing of files, interactive programming using subfiles and use of the AS/400 application development tools and utilities. The emphasis will be on procedural programming.

Credit Status
1 credit in the CPA / CPD program.

Learning Outcomes
Upon successful completion of this subject the student will be able to:

- Code and document programs to facilitate future maintenance
- Debug and successfully validate the results of test data
- Develop an RPGLE user defined function
- Develop a program using RDp (Rational Developer for Power Systems)
- Design, code, test and debug procedural programs using sequential and random file updates, program using interactive screens, multi-file I/O, tables and arrays, and data structures
- Use the traditional tools and utilities available on the AS/400 when developing programs (SEU, SDA, etc.)
- Develop and run a free format RPGLE program

Cheating and Plagiarism
Each student should be aware of the College's policy regarding Cheating and Plagiarism. Seneca's Academic Policy will be strictly enforced.

To support academic honesty at Seneca College, all work submitted by students may be reviewed for authenticity and originality, utilizing software tools and third party services.

Mode of Instruction
Students will be required to attend class weekly for lectures supported by visual aids. Additional reading will be required by the student to support his understanding of what has been taught. Lab time will be provided periodically during class time but students should realize that approximately 6 additional hours per week will be required by studying, reading and programming.


It is the student's responsibility to save documents, articles and notes that the instructor has provided on BlackBoard or in class. Students will not be able to access BlackBoard as of the last day of the student’s class.

Since this is a professional credit subject, marking standards reinforce professional practice by demanding legible, tidy work. Written materials should be well organized and grammatically correct, with proper spelling and punctuation.

Assignments

  • Students must retain a duplicate of all assignments.
  • Computer assignments should be documented to the instructor's standards.
  • Assignments must be handed in on the scheduled due date. Late assignments are penalized.
  • For particulars, please obtain standards, dates, etc. from your instructor.

Absenteeism and Tests
  • Students should be aware that absenteeism will impact on their ability to achieve satisfactory grades.
  • If you miss a test, you must provide the reason in writing to the instructor prior to the next scheduled class. If your reason is accepted, you will be permitted to write a make-up test. Otherwise, you will be given a zero for the test. You must submit an original doctor’s certificate identifying the date, length of time of expected absence and the specific reason for your absence, or other appropriate documentation.
Term Work and Final Exam
  • Students must attain a combined grade of at least 50% on term work and the final exam. Students must pass the final exam in order to pass the subject.
  • For further information on evaluation and academic standing, see a copy of the Academic Policy available at Seneca registration offices.

Grading is based on the following marking scheme:

Test (2) 40%
