I just found the atari mania site, and it's just great!!

Now I'm trying to remember the name of a game I used to have. Maybe you can help me!
This was on Atari 800XL that I was playing it... It was like seeing a tall building from the front, but you could see the elevator in the middle of the building. And you had to take your guy up and down the elevator, and deliver things? pick up things? I can't really remember... And sometimes you would stop at a floor and a dog would jump out from the apartment... So you would try to avoid those floors... I don't know what the point of the game was

Does that ring a bell at all?

Thanks for your help!
