Overview

This course (and its associated Part 2) have become the de facto standard introduction to the COBOL programming language for all those working in z Systems environments. This first course teaches how to write and maintain simple COBOL programs. It is taught using a combination of classroom tuition and hands-on practical exercises, and includes realistic case studies. As well as public presentations, this course is available for one-company, on-site presentations. When run exclusively for one organisation, the case studies can be customised to reflect the client's particular environment and work-load.

Objectives

  • describe the structure and purpose of COBOL programs
  • write, compile and test structured COBOL batch programs
  • code both IDENTIFICATION and ENVIRONMENT DIVISIONS
  • code data descriptions within the DATA DIVISIONS
  • access sequential files from COBOL programs
  • perform arithmetic operations in COBOL programs.
