In standard (character-based) Vermont Views, FULL_WNP represents the full screen of the display and is the parent for all subsequent windows. In Vermont Views for Windows, FULL_WNP represents the main application window. By default, FULL_WNP is sized to 80 columns and 25 rows. To change this default, you can call se_scrpos() prior to calling vv_init() . See New Library Functions for more information.
