West of House
You are standing in an open field west of a white house, with a boarded front
door.
There is a small mailbox here.
I
I don’t know the word “i”.
EXAMINE MAILBOX
I don’t know the word “examine”.
quit
I don’t know the word “quit”.
It just doesn’t seem to know any words. The same happens with every story file I’ve tried. The included EXE file works fine in Wine; maybe there’s something wrong with the way I compiled the binary (but I just typed gcc zorkmid.c -o zorkmid).
