Just continue on the next line, making sure that the starting line is
syntactically incomplete.  For example

  x +
  y

is a single statement "x + y", whereas

 x
 + y

is two statements.  You can do this by having unbalanced parentheses
in the first line, or ending it with an operator, or maybe other ways
(but it's too early in the morning for me to think of them).
