I'm going through Nick Bensema's "How To Draw A Playfield" but am not
getting very far. On page two, it lists a command that reads as
follows:
STA 0,X
I thought STA stored what followed the command, from memory
location or actual number, in the A register. The book on 6502
programming didn't mention anything about a comma like that. What am I
missing?
Also, just before it mentions that command, it mentions:
"Since X is already loaded to 0xFF, our task...."
What is 0xFF? That lower case "x" is what's throwing me. Is
"0xFF" referring to location FF on the zero page?
