Activating form items with DISPLAY

The methods for enabling or disabling fields and actions differs between Four Js BDS and Genero BDL.

WIth Four Js Business Development Suite (BDS), the program could enable and disable WIDGET="BUTTON", "CHECK" and "RADIO" fields of class "KEY" with the DISPLAY TO instruction:

DISPLAY "!" TO order.ord_status  -- Enables the field
DISPLAY "*" TO order.ord_status  -- Disables the field

With Genero BDL, use the DIALOG.setFieldActive() method to enable/disable fields, and the DIALOG.setActionActive() method to enable/disable actions (controlling form buttons). For more details, see Enabling and disabling actions
