The structured  data  types  are  user-defined  and  consist  of
  components.   Each  component  of a structured data type has its
  own data type; components can be any type.

  To express values of structured objects  (arrays,  records,  and
  sets),  you  can  use  a  list  of  values  called constructors.
  Constructors are valid in the TYPE, CONST, VAR,  and  executable
  sections of your program.  See the "HP Pascal Language Reference
  Manual" for examples of valid  constructors  and  examples  that
  show how to assign values to individual components of structured
  objects.
