SFLROLVAL

Additional information
SFLROLVAL is not implemented in general. However, some DDS programmers purposefully set the SFLROLVAL field to 0 or negative so that the Page Up and Page Down keys can be disabled (an error is issued when they are used), and they can define their own function keys to control the paging. In this case, they normally do not show the SFLROLVAL field. We check if the SFLROLVAL is invalid (0 or negative) and the SFLROLVAL field has display attribute non-display conditioned on. In this case we do not display the scrollbar.
