This intermediate course is ideal for individuals responsible for writing programs in Common Business Oriented Language (COBOL), or Programming Language One (PL/I) using DL/I to communicate with terminals in an IMS/DC system.
Delegates should be able to:
- Describe the basic control and flow of IMS/DC communications facilities.
- Understand the DL/I components and calls of a database application program.
- Modify a program in COBOL or PL/I to add IMS/DC functions.
On this course delegates learn how to write application programs that use Data Language One (DL/I) to process terminal input and output messages in an Information Management System / Data Communications (IMS/DC) system.
Course objectives include:
- Modify an IMS batch DL/I application program to function in an IMS/DC environment - receiving a message from a terminal and sending output messages to terminals.
- Handle exception conditions that may occur using DL/I functions.
- Work with Scratch Pad Areas (SPA) in an IMS-conversational program.
- Understand the application program considerations in using Message Format Services (MFS) and the system service functions data structures.
