CHB4 Codes
CHR$ (character) codes are recognized by BASIC as letters, numbers, other
characters, and commands. The command codes (0-31 and 128-159) tell BASIC
to change its output in some way (e.g., change the color of the characters
PRINTed on the screen, switch to upper/lower case mode, etc.). The remaining
codes represent the characters (letters, numbers, symbols, and graphics) the
Plus/4 recognizes.
