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.<br><br>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.<br><br>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.
COBOL Programming Part 1 - Foundation Level
An understanding of basic computing terms and techniques. For those who will be working in an IBM mainframe environment, a conceptual-level understanding of that environment and the ability to use TSO/ISPF is also expected.
- 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.
