SetColorMemoryAddress

SetColorMemoryAddress();

Description

The ScreenMemory and ColorMemory pointers are primarily used to modify the characters displayed on the screen.

ScreenMemory typically points to the screen memory area and ColorMemory does the same in the color memory area. When setting the ScreenMemory to point to a location on the screen you will often want to also set the ColorMemory as well. This command will calculate the correct address for the ColorMemory using the current ScreenMemory address.

This is an optimised command and is a quite fast way to align the ColorMemory pointer relative to the ScreenMemory.

Example

// Make sure the pointers are set up DefineScreen(); // set the ScreenMemory pointer to 16 characters across ScreenMemory := $1e10; // set the ColorMemory pointer to the same position but in the color memory area SetColorMemoryAddress(); ScreenMemory[ 0 ] := 1; // put an A character this location on screen ColorMemory[ 0 ] := RED; // make this character red
