To summarise, the total mode (0) character set available is
shown below. Note that these are the characters displayed if the
codes concerned are written directly into the screen RAM
using POKE statements or from a machine code routine.
Note that when the PRINT CUR$ (N) command is used
,
rather than
POKE, the BASIC interpreter performs code conversion to make the
display conform more closely to normal ASCII standards. Hence
decimal codes
0 -
31 become non-printing control codes, while
codes 64-95 become those for the normal alphabetic capitals. As
there are no lower-case characters available, codes 96-127
duplicate the characters for codes 32-63. Codes 192-255 are used
for the inverse alphanumerics, and codes 128-143 for graphics
(with colour set by the COLOR M,N command).
