The  statement  token  can  be  expanded  to  display  any  valid  BASIC
  statement.   The  statement token is available in all of the compilation
  units and can be repeated as often as you wish.

  When you call the Language-Sensitive Editor to  modify  a  program  unit
  already  in  existence,  the statement token is not available.  However,
  you can enter the beginning of any valid BASIC statement and then expand
  it with the editor in the usual way.
