That Vert. Line. stands for Verticle *Linearity* and simply establishes the
proportion of spacing between lines of scan top relative to bottom.  The effect
is to make possible *TALLER* char's at the top and decreasing in height in each
line closer to the bottom (or vice versa).  The Vert. Ht. increases the spacing
between ALL lines (or decreases).  If you do this adjustment without pro-
portionately adjusting the Horiz. Width of the scan, you get the stretched up
display described.  **For safety's sake, please use a plastic screwdriver to
make this adjustment; metal blades can result in an electrifying experience**
