BT05 - COBOL Programming Workshop - 5 Days


Course Description

The course is aimed at developers not familiar with COBOL program development. This course covers all aspects of Programming with COBOL. The course teaches the design, writing and testing of COBOL programs. Many exercises are performed by the developer to ensure that the statements taught are fully understood and practical experience is gained.

The course contains many 'hands on' exercises, whereby the delegate writes many COBOL programs which contain the full set of COBOL verbs. It is recommended for IT professionals who need to learn how to develop COBOL programs.

Unlike many other training companies who choose to run 2 separate COBOL training courses (e.g. COBOL Programming Part 1 - Foundation Level and COBOL Programming Part 2 - Advanced Level) our COBOL courses include full coverage of COBOL syntax (other than the SORT command which is rarely used). The course also includes KSDS VSAM file access (if required).

COBOL, COBOL2 and Enterprise COBOL syntax is included.

As an alternative to this course, we also offer a 3 day COBOL Overview (course code BT25) and a 10 day option (intended for new starters) which additionally covers TSO, ISPF and JCL (course code BT35).

Pre-requisites

This course can run on both IBM Mainframe and PC Platforms. Our PC based course uses a Fujitsu COBOL compiler running on a Windows platform.

If this course is to run on an IBM mainframe, prior knowledge of TSO/ISPF and JCL is required. This can be gained by attending course BT02.


Objectives

Whilst covering the basics of COBOL programming and how it is used, this course also aims to give an insight into structuring COBOL programs, COBOL verbs, manipulating data, and testing COBOL programs.

On completion of this course the student will be able to:

  • Develop Structured COBOL Programs
  • Understand and Use COBOL Verbs
  • Develop COBOL programs using the available verbs
  • Develop and Test COBOL print programs
  • Develop and Test COBOL programs accessing different types of files

Environment

Development will be performed using:

  • IBM Mainframe
  • Off mainframe using a PC based COBOL compiler

Customisation

For on-site courses (i.e. at your premises), we are more than happy to tailor the course agenda to suit your exact requirements. In many cases, we are able to build your in-house standards and naming conventions into the delivered course.

Course Format

Practical sessions make up a large part of the course, allowing delegates to demonstrate and reinforce the lectures given. During these sessions the delegate will gain experience of writing and testing different types of COBOL programs using the various COBOL verbs available.

Examples are used extensively, ranging from simple code snippets to full applications with complete 'real world' functionality. These are supplied at the start of the course and it is encouraged that the delegates execute and 'experiment' with these under the instructor's guidance as they are introduced.

These examples are available to take away, along with the delegate's own work.

The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
