Your typical BASIC-running machine didn't use escape sequences and there were often ways to jazz up characters built directly into the language, e.g. https://www.calormen.com/jsbasic/reference.html#:~:text=black%2Don%2Dwhite-,FLASH,-Set%20output%20mode https://www.calormen.com/jsbasic/reference.html#:~:text=blac...

No, chr$() was intended for use to create strings containing characters that could not be typed on the keyboard.

  It converted a numeric value into a string. Typing on the keyboard didn't have all that much to do with it and many BASIC REPL's supported shoving control chars into string literals via a variety of additional shenanigans.
