This post discusses a clever technique for optimizing the way the Commodore 64 BASIC programming environment clears a high-resolution screen. Several users shared nostalgic experiences and technical insights on utilizing memory management and exploiting graphical buffers for better performance. The conversation highlighted historical programming practices, such as using memory addresses creatively to enhance speed, albeit at the risk of system stability. Users also debated methods of string manipulation within BASIC, particularly around the efficiency of character concatenation versus string concatenation, noting the differences in execution speed and memory handling. Additionally, the extensibility of C64 BASIC is praised, with pointers being a crucial element in manipulating memory layout effectively without corrupting essential system functions.
