Keyboard keys properties

Keyboard Keys have the following properties:

Key Name

The name assigned to the key. Enter a value of 16 characters or less. You can define a meaningful name for any key on your keyboard, and use these keys in any keyboard command. For example, you can define the F1 key as the Login key. When the Login key is subsequently referenced in the system, it refers to the F1 key.

You can assign a key name to any key on the keyboard (including the alphanumeric keys A-Z, a-z, and 0-9). However, after a key is defined as a command key it can only be used as a command key. If you do assign a definition to an alphanumeric key (for example the character A), then that key can not be used as a data key. Each time it is pressed, the definition for the key is recognized and not the keyboard character itself. Keyboard key definitions are usually only used with non-alphanumeric characters (for example the function keys).

Key Code

The code assigned to the key name. Enter a value of 16 characters or less. The Key Code is what links your Key Name to the actual key. You can specify the key code either as a hexadecimal value or use the standard label already associated with the key.


Any useful comment. Enter a value of 48 characters or less.

Extended forms fields

The following fields are implemented with extended forms (press F2).


Determines if the key is echoed on the screen (when the key is used). Enter a value of 8 characters or less.



(Display (echo) the Key Name when the key is pressed. The key name is displayed on the graphics page in the keyboard entry line - AN1)



(Do not display (echo) the Key Name when the key is pressed)

This property is optional. If you do not specify Echo, Echo defaults to True.

Keyboard Type (16 Chars.)

The type of keyboard. This field is only necessary if you have more than one type of keyboard on the same system.

If you do have more than one type of keyboard, use Keyboard Type 1 for your first type of keyboard, use a separate number for each type (1, 2, 3, etc.), and define keys for each keyboard. You can use the default (Type 0) for common keys.
