The two programs "vn7to8" and "vn8to7" convert between the 7-bit VIQR format for Vietnamese (Viet-Net like) and the 8-bit VISCII data formats (RFC 1456). The current supported version is VISCII 1.1. The program "vn80to81" converts files from VISCII 1.0 to VISCII 1.1. For complete details, please see the Viet-Std documents published elsewhere.
