COBOL Programming Part 2 - Advanced Level


This course is the essential second part of the definitive introduction to COBOL programming that starts with the course 'COBOL Programming Part 1 - Foundation Level'. Introducing programmers with some experience to the more advanced features of COBOL, this course completes the lessons on 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. The course is taught using a combination of formal classroom sessions and 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.

Objectives

On successful completion of this course you will be able 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.

Who Should Attend

Trainee or junior programmers who have already been writing or maintaining COBOL programs.

Prerequisites

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.

COBOL Revision


Attendees will be required to write a COBOL program in order to demonstrate that they have a sufficient level of understanding of the language. This will also enable the instructor to identify any areas that require attention.

Table Handling

PERFORM...VARYING and TABLES; two and three dimensional tables; indexed tables: SET, PERFORM... VARYING with indexes, SEARCH; INITIALISING TABLES; OCCURS DEPENDING ON; complex ODO.
How tables (arrays) are used within COBOL programs.

Subprograms

CALL statement; LINKAGE SECTION; ENTRY; GOBACK; EXIT PROGRAM; CANCEL; subprogram examples; dynamic CALLs.
Describes program linkage, how data is passed from one program to another and distinguishes between static and dynamic linkage.

VSAM File Handling

RELATIVE and INDEXED FILE-CONTROL entries; VSAM status keys and return codes; READ; WRITE; START; REWRITE; DELETE.
Showing all aspects of accessing VSAM files in a COBOL Program

The SORT Facility

SORT FILE description entry; determining SORT success; SORT verb; RELEASE; RETURN.
How to invoke SORT from a COBOL program.

Miscellaneous COBOL Statements

SET; INSPECT; STRING; UNSTRING; SPECIAL-NAMES paragraph; CURRENCY SIGN and DECIMAL POINT clauses; CLASS clause.


What the students say

Thoroughly enjoyable experience. Having an instructor with such a level of interest, experience and knowledge made the training much easier and enjoyable.
