Fibonacci Generator v$VERSION
Usage: $0 [-ch] [number]
-c\tPrint output in a single column (default is rows)
-h\tPrint help text (what you're reading now)
Include how many numbers in the sequence you want,
otherwise it defaults to 100.
END

my $stop = shift || 100;
print $x;
print $y;
for ( 3 .. $stop ) {
( $x, $y ) = ( $y, $x+$y );
print $y;
