VMS Help PASCAL, Attributes, Alignment, UNALIGNED  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The UNALIGNED attribute specifies that an object can be  aligned
  on  any  bit  boundary.   An  UNALIGNED  variable cannot have an
  allocation size greater than 32 bits.

  See the  "Compaq  Pascal  Language  Reference  Manual"  for  the
  complete description of using the UNALIGNED attribute.
