Audience
This course is for application developers who need to write, maintain or support VME COBOL applications. It is also suitable for staff requiring a COBOL refresher course, or those who are unfamiliar with the VME system.
Prerequisites
This is an intensive course where delegates should be computer professionals with an aptitude for programming. Experience with another programming language would be beneficial but not essential. Those very new to IT should consider the more comprehensive, leisurely paced VCOB: COBOL for VME.
Duration
5 days. Hands on.
Course Objectives
During this course you will learn to use all aspects of the COBOL language, along with the required SCL and Data Dictionary usage to input, compile, test and debug programs in a VME environment.
