Figure 5-3. CeO Used in DEC VT220
Using the characters created for the DEC VT220 will not cause any problems
when used in emulation mode, because a large cell (8 by 16 dots) can hold a small
cell (8 by 10). You can load the ORCS characters in the same way as you do
when using a DEC VT220. A DEC VT220 ORCS character is automatically
placed in the DEC VT220 area as shown in Figure 5-4. This area is equivalent to
a DEC VT220 cell .

A large cell can provide enhanced capability. You can use the additional dots in
Figure 5-4 to design a more complex character. When designing a character
using additional dots, note that:
Dots in column 8 of the previous character continue to the dots in column 1
of the next character on the screen
