Mainframe Training : IMS Transaction Monitor with Message Format Services (MFS)

IMS Transaction Monitor with Message Format Services (MFS)

Mainframe Training Overview

The course is a series of lectures, discussions, written exercises, and programming exercises dealing with the concepts, capabilities, and coding for IMS Transaction Monitor programs.

Students will design terminal screens and code Message Format Services (MFS) macros to implement those screen designs.

The students will modify a skeleton COBOL program to receive an input message (from an on-line terminal), process that message, and send a message (to an on-line terminal), change screen attributes, send a message to another program, and use PFF keys.

The Batch Terminal Simulator (BTS) is used for Program testing.

Mainframe Training Learning Objectives

Upon successful completion of the course, each student will be able to -

Explain the relationship among terminals, messages, programs

Code MFS macros that describe on-line screens and messages

Modify a skeleton COBOL program to access IMS terminals

Code Data Language I (DL/I) calls for the following -

Get a message (GU) from a terminal
Insert a message (ISRT) to a terminal
Insert a message (ISRT) to another program
Change (CHNG) the destination for a message

Code program IO-AREAs to match a terminal messages

Code status code checking to determine each call's success

Modify Batch Terminal Simulator (BTS) control statements

Code the use of PF Keys

Change screen attributes from the program

Mainframe Training Audience

This course is for students who must understand and code programs that run in the IMS Transaction Monitor environment.

Mainframe Training Prerequisites

IMS Database programming experience is NOT required. Six months experience with COBOL, TSO/PDF and JCL is required.

Mainframe Training Course duration
