VMS Help PASCAL, Predeclared Routines, Misc, ODD  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The ODD function returns a Boolean value that indicates  if  the
  parameter is odd.

  Syntax:

     ODD( x )

  The parameter 'x' must be of  type  INTEGER  or  UNSIGNED.   The
  function  returns  TRUE  if the value of 'x' is odd and FALSE if
  the value of 'x' is even.
