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
5 days
