Now assume that the channel accesses its next data parcel using Pointer3 again, this time with
length given by Length3. In this case the channel continues to the next line of the link table, and
begins reading the memory segment specified there. As before, the channel concatenates memory
segments from as many link table entries as necessary to obtain the required number of bytes
(Length3).
Similarly, the next data parcel is obtained by using Pointer3 yet again, this time with length given
by Extent4.
Assume that for the current descriptor type, the Extent4 data parcel is the last one to be accessed
through Pointer3. Then the link table entry that supplies the last memory segment for Extent4 has
the R bit set, signifying that this is the last entry in the chain of link tables.
shows how the pointer dwords should be used with the various descriptor types to load keys,
