TPF Introductory Class

Introduction to TPF 4.1 Programming

Overview
This 10 TPF training class is designed to give an in-depth overview of the concepts of TPF and then introduce the student to the TPF macros required to enable new programmers to write TPF Application programs. The TPF Technical Overview course is taught as the first 2 days of this 10 day class to give the students an introduction to the major concepts of TPF. Each session concludes with exercises to reinforce student knowledge of the concepts taught. On completion of this class there is an optional 2 week Programming Workshop, during which the students develop a programming project from design to implementation.

Pre-requisites
Students should have completed the S390 Assembler Class or have prior commercial experience of Assembler Programming.

Audience
Students who are required to write and maintain TPF application programs, and staff who require TPF application programming knowledge in their job.

Student Numbers
The maximum recommended student to instructor ratio is 12:1

Objectives
By the end of the course, the delegates will be able, with the aid of course notes to:

· Identify and describe the features and functions of a TPF system.
· Identify and describe the coding principles and restrictions used in TPF application programming.
· Given the necessary specification, code a TPF segment in Assembler language.
