# Natural Parameters and System Variables

The following Natural parameters and system variables are evaluated in Natural for Ajax applications and sent to Application Designer:

- `DC`

  The character assigned to the `DC` parameter is used in the representation of decimal fields in Application Designer.

- `DTFORM`

  This parameter is used for all date fields in Application Designer pages. In your application, the date is shown according to the setting of the `DTFORM` parameter.

- `EMFM`

  The value of the `EMFM` parameter is evaluated for fields in Application Designer pages for which a dynamic edit mask has been assigned. See also Usage of Edit Masks.

- `*CURS-FIELD`

  Identify the operand that represents the value of the control that has the input focus. When the Natural system function `POS` is applied to a Natural operand that represents the value of a control, it yields the identifier of that operand.

- `*LANGUAGE`

  Change the language while an application is running. See also Multi-Language Management.
