CG03 - CA-TELON to Casegen Conversion
Duration3 Days (customisation)
Availability

Course Description

The course is aimed at sites converting from CA-TELON to Casegen and is aimed at developers already familiar with program development using CA-TELON. The course covers all aspects of On-line and Batch Programming with Casegen. Many exercises are performed by the developer, tailored to the client's Casegen operating environment, to ensure that the statements taught are fully understood and practical experience is gained.

Pre-requisites

Hands on experience with CA-TELON.

Objectives

To teach the CA-TELON developer the necessary skills to develop similar programs using Casegen.

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

  • Develop structured Casegen Batch and On-line Programs
  • Develop screen based programs
  • Understand and use the different validation methods within Casegen
  • Generate Database access
  • Customise the generated data access
  • Develop list programs
  • Understand and use the various custom code points within a Casegen program
  • Understand and manipulate Casegen generated variables
  • Develop report programs
  • Understand and develop modular batch programs
  • Understand and and develop sub-programs

Environment

Development will be performed using:

  • Casegen

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 Casegen Batch programs using the various program structures 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.
