This function determines whether windows are available in Arbortext Editor. If the type is not supplied or is 0, this function returns 1 if windows are not available or 0 if windows are available. Windows are not available if Arbortext Editor is run in -c (command) mode or -S (server) mode. To test for a specific non windows mode, then type should be set to 2 for -c (command) mode or 3 for -S (server) mode.
