@UI

This function has been deprecated and will not be supported in future releases. It should be replaced in all existing rule definitions with SCREENFIELDVALUE. The UI function takes a single parameter that is the field index for the currently displayed screen and returns the value of that field. The field index is a 0-based index. The parameter must be between 0 and the total number of field definitions on the current screen minus 1.

The value of the specified field is evaluated in the context of the function call. The UI function supports the Boolean, integral number, decimal number, string, and property return types.
