SCREEN MEMORY MAP, COLOR MEMORY MAP, Color Codes - 40 Columns

The following maps display the memory locations used in 40-column mode (C128 and C64) for identifying the characters on the screen as well as their color. Each map is separately controlled and consists of 1,000 positions.

The character displayed on the maps can be controlled directly with the POKE command.

The Screen Map is POKEd with a Screen Display Code value (see Appendix D). For example:

POKE 1024,13
