ILE COBOL Programmer's Guide


Accessing Display Devices and ICF Files

You use display files to exchange information between your ILE COBOL program and a display device such as a workstation. A display file is used to define the format of the information that is to be presented on a display, and how that information is to be processed by the system on its way to and from the display. ILE COBOL uses TRANSACTION files to communicate interactively with a display device.

You use Intersystem Communication Function (ICF) files to allow a program on one system to communicate with a program on the same system or a remote system. ILE COBOL uses TRANSACTION files for intersystem communication.

See Using Transaction Files for a discussion on how to use TRANSACTION files with display devices and ICF files.
