If you have numerous fields on a form, without writing specific code to control navigation, Uniface assumes a left to right navigation path through amendable fields. This may not suit many users who instead wish to control the field order in navigation. This then requires code to be added to a form, every next/prev trigger and coding to control if/when fields are/are not available. Add to this then the complexity of handling navigation through fields ($prompt) if some may conditionally be promptable or not. If instead, a weight/order value could simply be assigned to each field, and Uniface followed that order (skipping non-promptable fields), screen navigation could be controlled far more simply and reliably.
