While browsing through the C64 memory map, I noticed a kernal routine specifically for clearing the screen. While I prefer the later methods I outlined in my earlier post (here), it’s a quick one liner to get the job done, and I will be making use of it in coming examples to keep the code length down.

The routine is found at $e544.

Clear screen kernal routine

I love finding little things like this as I explore the memory map. Sometimes it useful routines, other time it’s blocks of memory or registers designed to do something I’ve been thinking about in my head. It’s a shame they don’t make systems like this to develop for anymore.
