一昨日の記事で書いたPC-8001向け「自己書き換え」直線描画・消去プログラムだが、256×256ドットの仮想画面のうち中心部分160×100ドットを切り出すやり方になっており、画面外であっても1ドットずつ非描画処理をおこなっていた。つまり、全てのドットが非描画であっても1ドットずつ処理をおこなっていて、かなり無駄だったりする。完全に画面外の場合には、始点から終点への座標移動だけをおこなえばいい。
DEレジスタに始点のXY座標、Cレジスタに角度(2π/256刻み)、Bレジスタに長さを渡すと、PC-8001の160×100ドット画面に直線を引きつつ、DEレジスタに終点のXY座標を返すZ80プログラムを、以下に示す。XY座標は画面中心を(0,0)としており、左上隅が(B0H,32H)である。
