All my Atari programs typically began by first designing the display list. Code followed thereafter. I had a dickens of a time writing code if I couldn't picture the visual layout in my head. Designing the display list first helped me visualize the display while I was coding. It also helped when designing the display list interrupt code.
The display list shown below is for the character editor. For the map editor, only the first few rows of the display were static (the command window); the rest of the display list (the map part) was generated procedurally.
You may notice that all my notes are in pen. I guess I liked using pens more than I liked being able to make corrections.
