The Display Interface

The Terminal Manager's keyboard interface has been discussed above. The display interface can also be configured. Its task is to implement, for a particular terminal, those program instructions that specify display attributes. You can accomplish most desired display options by defining, in the terminal database file, the actions that terminal function codes will take. You can specify some other display options by assigning values to special keywords in the ACUCOBOL-GT runtime configuration file.

The steps listed below describe, in a simplified way, the overall process from COBOL statement to screen display:

Restricted Attribute Handling also describes the runtime configuration file options. The terminal database file function codes and values are described in The Terminal Database File.
