COBOL programming - part 2

The training COBOL Programming is composed of 2 separate courses: in Part 1 the participant becomes familiar with the basic COBOL programming techniques, in Part 2 the more advanced topics are treated.

At the end of Part 2, the participant:

  • knows the complete COBOL syntax;
  • is able to develop, debug and execute COBOL programs.

This course is also available as a combined course (Parts 1 and 2); see COBOL programming: fundamentals course.


No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please let us know.

Intended for
