A few years ago the Americans sent a spacecraft to examine Venus. However, when it
was near Venus, it was necessary to alter its direction slightly by means of a computer.
They tried to do this by typing the Fortran statement: DO 3 1 = 1.3. Unfortunately, this
statement was incorrect because there was a comma instead of a full stop. The correct
statement would have sent the spacecraft very close to Venus, but the incorrect statement
sent the spacecraft into outer space. Several billion dollars were wasted as a result of such
a mistake.
