This manual describes several "extra" commands that were created for geoSHELL2.2 after geoSHELL was released.  These were available for free downloading to geoSHELL users from various online services and are now being supplied with geoSHELL. Previously, these commands were supplied on a separate disk known as the "geoSHELL extras", but they can now be found on the geoSHELL disk (side 2 in 1541 format).
