Assembler Language Programming

I.     Course Prefix/Number: CIS 235

       Course Name: Assembler Language Programming

       Credits: 4 (3 lecture; 2 lab)

II.    Prerequisite

Recommended: Knowledge of any programming language.

III.   Course (Catalog) Description

Course introduces programming using the Assembler Language to solve business-related problems. Content includes compiling, linking, executing, and debugging programs written in the System/370 assembler language; performing arithmetic operations and input/output operations, and using the packed decimal and binary instruction sets. Programming logic includes control breaks, subroutines, structured coding, and table processing.

IV.   Learning Objectives

A.    Write programs that use unit record DTF’s with and without work areas, produce edited output, perform calculations using both the decimal set (packed format) and the binary set (registers) instructions, and process tables using sequential search and bas/displacement address calculations.

B.    Describe the internal configuration of primary storage during the execution of assembler language instructions, the machine language instruction formats, the principles of storage addressing, the standard linkage conventions.

C.    Use assembler listings, maps, and core dumps to analyze and debug problem programs.

D.    Understand the relationship of high-level computer language to the IBM 360/370 computer.

V.    Academic Integrity

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• 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.
