COBOL Programming Part 1 - Foundation Level
Introducing new programmers to COBOL, this course teaches how to write and maintain simple COBOL programs. It is taught using a combination of classroom tuition and practical exercises, and includes realistic case studies that can be based on the client's particular environment and work-load.
The RSM Professional Portal
All course attendees will be given free access to the RSM Professional Portal. This provides:
- on-line access to the course notes (full colour, searchable and regularly updated)
- access to the RSM Technical Forum.
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)
£1695 (ex VAT)
