IMS DB Application Programming (U3717)
or 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
Obiettivi
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 the exception conditions that may occur using DL/I functions
