COBOL Programming Part 1 - Foundation Level
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.
The next step
To complete your COBOL programming skills, the next essential course to take is COBOL Programming Part 2 - Advanced Level.
On successful completion of this course attendees will be able to:
- 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.
Who Should Attend
Trainee or junior programmers who will be writing or maintaining COBOL programs.
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.
Fee (per attendee)
£1850 (ex VAT)
