SUMMARY:   The course explains the concepts, capabilities, and coding for IMS Data Communications programs. Participants will create screens and code Message Format Services (MFS) macros to implement those screen. They will work with COBOL programs to send/receive/process messages. Screen attributes, message switching, and PFF key programming is included. Testing with Batch Terminal Simulator (BTS) and the clients tools will be included. AUDIENCE:   This course is designed for participants wanting to code and maintain programs that run in the IMS DC environment. PREREQUISITES:   IMS Database programming experience is NOT required. Six months experience with COBOL, TSO/PDF and JCL is suggested. Note: VMware can be used for the IMC/DC environment. DURATION:   4-5 days based on student’s experience. OBJECTIVES:   At the end of this course, delegates will be able to: Explain the relationship among terminals, messages, and programs. Code MFS macros that describe on-line screens and messages. Modify COBOL programs 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’s 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.
