Notation for Messages
Line Spacing. If the syntax of a command is too long to fit on a single line, each continuation 
line is indented three spaces and is separated from the preceding line by a blank line. 
This spacing distinguishes items in a continuation line from items in a vertical list of

ALTER [ / OUT file-spec / ] CONTROLLER
 [ , attribute-spec ]...
