+構造体とは, 各成分の要素が名前でアクセスできる固定長配列と思ってよい. 
+各構造体は名前で区別される. 構造体は, @code{struct} 文により宣言される. 
+ある型の構造体は, 組み込み関数 @code{newstruct} により生成される. 
+構造体の各メンバは, 演算子 @code{->} によりアクセスする. 
+メンバが構造体の場合, @code{->} による指定は入れ子にできる.

+A structure data type is a fixed length array and each component of the array
+is accessed by its name. Each type of structure is distinguished by its name.
+A structure data type is declared by @code{struct} statement.
+A structure object is generated by a builtin function @code{newstruct}.
+Each member of a structure is accessed by an operatator @code{->}.
+If a member of a structure is again a structure, then the specification
+by @code{->} can be nested.
