Interface Level 2:
No additional parameters are required for interface level 2.
Function keys can be assigned to the CALL dialog command on the ACTION attribute of the key item (KEYI) tag. When the function key is pressed, the UIM calls the specified program.
The CALL dialog command is assigned to a function key to process requests that are specific to the application. These requests either do not have a command interface or require more knowledge about the current application than can normally be passed through a command.
The application can perform most functions, but the application developer must be aware of the effects of changing dialog variables, displaying other panels, and so on.
