Water bottom pointer (items VP and VV)

By means of the value pointer (item VP) a vector can be loaded to the HCU or ICU_HPI option board. Next with
item VV, the selected data is returned. Item VP consists of 4 positions, in the middle separated by a '.' or ','; v w ,
x y (or v w, x y). The values for the value pointer are listed in table 5 – 3 together with the obtained data.
