Standard Function Keys

CA 2E provides a number of standard function key meanings, such as *Exit, *Delete, or *Next page. Each meaning is assigned a function key. These meanings conform to the design standards. To change the user interface for an application, you reassign the function key and regenerate the code.

Each function key has a specific value out of a list of standard values. The standard function key meanings are controlled by list (LST) conditions attached to the *CMD key field. Each available function key is specified by a value (VAL) condition attached to the same field. Assigning a particular function key value condition to a given list condition assigns it a particular meaning. The CA 2E screen design and generator programs use the assigned value.

The following table shows the shipped function key value defaults.

For...	Command Key	Description
All Programs	F1	Display Help text
	Enter	Validate Input
	F3(Exit)	exit without update
Where appropriate	F12	Previous screen
	F4	prompt
	F5	Reset
	F7,Roll Up	Next page
	F8,Roll Down	Previous page
	F9	Add/Change
	F11	Delete

You can display standard function key meanings by accessing the Edit Field Conditions panel. You can access this panel from an action diagram or from the Edit Field Details panel.

Note: A good practice is to define all function keys referenced in action diagrams as lists (LST) and not values (VAL). You can then change the description of the function key where ever it displays by changing the list condition.
