You can use this entry point only within a ScreenMan form, in all places where M code can be placed on the form.
This extrinsic function retrieves data from a form-only field or a computed field.
If, while a form is running, a call to GET^DDSVALF fails, ScreenMan prints an error message in the Command Area.
