Course Description: This course describes how to create an interactive application. The course begins by describing the role a display file plays in an interactive application and how a display file is created. You will see the data description specifications (DDS) source statements most commonly used for a display file. The course then considers the requirements for an interactive CL program. You will see how to declare a display file in a CL program and how to display data at and receive data from a workstation.
You will also see the requirements for a multiple request terminal (MRT) program. An MRT program is one that communicates with multiple workstations. The course ends by describing how to override certain attributes in a display file.
After completing this course, you should be able to: Interpret the DDS statements used to define a display file Code a CL program that uses a display file to communicate with a workstation user Code a multiple request terminal (MRT) CL program Override certain attributes specified in a display file
