The %INCLUDE directive inserts the contents of  a  file  at  the
  location  of  the  directive  in  the code and has the following
  form:

  Syntax:

  %INCLUDE 'file-spec [[/[[NO]]LIST]]'

  The 'file-spec' is the name of the file to be included.

  The /LIST qualifier indicates that the included file  should  be
  printed  in  the  listing  of  the program if a listing is being
  generated.  If not specified, the default is determined  by  the
  use  of  compilation  switches.  Use of this parameter overrides
  compilation switches.

  See the "HP Pascal Language Reference Manual" for  the  complete
  description of using the %INCLUDE directive.
