char pointer bend to another address

[boriel]

To change only the character "K" I suggest to use UDG (User Defined Graphics).
If you compile with the --sinclair option, the compiler will enable several features at once, to maximize compatibility with Sinclair's ROM BASIC.
Then you can POKE at USR "k" + i, using READ and DATA:

Code:

FOR i = 0 TO 7
   READ a
   POKE USR "k" + i, a
NEXT i

REM PRINT the UDG "k"

PRINT "\K \K"

DATA 85, 170, 85, 170, 85, 170, 85, 170
