Figure 18·2. Double high and wide character.
Sorry, but you 7-bit users will have to skip to "Building Symbols from
a Small Core Set," below.
The list above makes it easy to remember the four characters that
will make up the "font" for each letter, but in order to define letters in
groups of four, you'll have to modify the definition process. Fortu-
nately, the ASCII numbers that represent the four different versions of
each character have a consistent pattern. That pattern is shown in
Table 18-1.
