Abstract
The specification shows and describes a visual display of the CRT variety wherein column separator lines may be displayed intermediate character matrix positions as an operator aid. The visual column separators further do not require that any character position be used or encroached upon and where limited spacing occurs between character forming dot matrices, logic delays may be utilized in the video modify circuitry to displace the separator line and thereby visually distinguish such separator line from any adjoining character.
