What is the C64 game in which user enters commands and there is a robot that chases you?

I remember playing a game in which you start out on a road and you see a robot. You enter commands like "pick up the rock." If you enter something crazy is uses the word "absurd" in some form. If I recall correctly, there are no graphics involved in the gameplay. Of what game am I thinking?|||Could be either Suspended, Planetfall or perhaps Stationfall authored by Infocom, along with several other text adventures like the Zork trilogy and beyond. Great games.
