This statement
writes data sequentially
to
the specified
file.
When
you
first
open
a
file
for sequential output,
a pointer
is
set to
the
beginning of
the
file,
therefore
your
first
print#
places data
at
the
beginning of the
file.
At
the
end of each
print#
operation, the pointer
advances, so the
values
are written in
sequence.
