COBOL Programming Part 2 - Advanced Level

Introducing programmers with some experience to the more advanced features of COBOL, this course teaches how to write new programs and how to maintain existing ones. As attendees will be writing testing and debugging actual programs, the use of COBOL logic will be reinforced during this course. It is taught using a combination of classroom tuition and practical exercises, and includes realistic case studies, which can be based on the client's particular environment and work-load.

Prior knowledge

The ability to use TSO/ISPF and an understanding of JCL is expected, along with prior attendance on the course COBOL Programming Part 1 - Foundation Level or equivalent experience.

Delegates will learn how to 

  • code and call COBOL subprograms
  • define and access tables using either subscripts or indexes
  • use the COBOL internal sort facility
  • define and use VSAM files.

Outline
