Horizontal blanking positions The VDC can adjust its horizontal blanking interval to blank a portion of the screen. These locations control the horizontal width and position of the blanked area. If the blanked area extends onto the active portion of the screen, any text under the blanked area is only covered, not erased. The value in register 34/$22 determines the rightmost blanked column, and the value in register 35/$23 determines the leftmost blanked column. The blanked area extends the entire height of the screen.
The value in register 34/$22 must be less than the value in register 0/$00; otherwise, the entire display will be blanked. The value in 34/$22 here must also be greater than the value in register 35/$23 to prevent an entirely blank display. The default values for these locations are 125/S7D and 100/$64, respectively. This positions the blanking interval entirely outside the active screen area. For purposes of blanking an area of the screen, a value of 6/$06 in these registers corresponds to the leftmost column of the standard screen and a value of 85/$55 corresponds to the rightmost column.
The best analogy is to think of them as two curtains on both sides of a stage. You can draw the left and right curtain independently.
