THEORY OF OPERATION
SEC1'ION 4
A, C, G, J, 0 Q, 5, U, V, and Y.
In Figure 4-3 "V"
is
used as an example
of how characters in this group are formed. The basic operations for creating the
other upper case characters also apply to this group.
But in this group a non-dis-
playable control dot can exist in C-2, L-l through L-6.
As shown in Figure 4-3, whenever a control dot is present in a line, CL-I,
L-2, and L-S), that line is shifted one-half dot position to the right. (Note that
a control dot is never used in L-O for this group of characters.) This feature makes
the characters displayed in this group more natural looking by creating an effective
7 x 14 dot area in an actual 7 x 7 dot area.
