  RELATE

  【1.0 build 15 追加】
   RELATE <assocA> TO <assocB>[, assocC, ...]

   Type: statement

   This statement creates a relation between associative arrays.
   Effectively this will result into duplication of settings; an index in
   array <assocA> also will be set in array <assocB>. A previous
   declaration of the associative arrays involved is required. Example:

   DECLARE human, mortal ASSOC int
   RELATE human TO mortal
   human("socrates") = TRUE
   PRINT mortal("socrates")
