Syntax:  SET PLACEHOLDER BODY LINE body_string indent_type

              defined_placeholder defined_language

  Specifies a body line of a nonterminal type placeholder.

  The body of a nonterminal placeholder is the text of the placeholder
  expansion; when a nonterminal placeholder is expanded, the
  placeholder name and enclosing delimiters are replaced with the text
  of the placeholder body.  This command is valid only for nonterminal
  type placeholders.

  The parameters for this command allow you to specify the format of
  the body when it is expanded.  See the parameter glossary for a
  detailed explanation of how these work.
