This is a game involving a man chasing after a bug.
CONTENTS
The bug moves according to random numbers.
The man chases the bug and kills it. eli)
The man moves by using the GJ + C§J keys. (INKEY$ is used)

Each time the man moves one space, so does the bug. (Sometimes the bug will
stay in the same place.)
Initially,
the man is in position (0,0).
The bug is placed at a position that was chosen at random.
Hints are displayed as distance.
The distance is displayed by the ASS (X -a) + ASS (Y -b) equation.
The initial energy level is 100. This decreases by 1 with time.
Each time that a bug is killed, the energy increases by 5, 10, or 15. (The
amount is chosen randomly.)
The score is determined by how many bugs were killed when the energy level
reaches
O.
(The position of the bug may "warp" when cornered.)
The program can be started by either pressing RUN (ENTER) or @0 CXJ .
