Hi, this was the first assembler prg. I used around 84/85. It's just great. Editor, Assembler and debugger in memory at the same time. This enabeled you to work real fast. Comands were given by typing them into the comandline at the bottom of the editor screen. The assembler was very fast. The author was well known in the german atari scene. He also wrote great games like "cavelord" and "schreckenstein". Another great tool was "Design Master". Check them out!
