/sys$common/syshlp/helplib.hlb PASCAL, Attributes, Alignment, ALIGNED  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The ALIGNED attribute indicates the object is to be aligned on a
  specific memory boundary.

  Syntax:

     ALIGNED [[( n )]]

  The default alignment of an object depends  on  its  size.   The
  constant  expression  n  must denote an integer.  If you omit n,
  the default is 0, indicating byte alignment.

  An aligned object is aligned on the memory boundary indicated by
  n.   The constant expression n indicates that the address of the
  object must end in at least n zeros.  ALIGNED(0) specifies  byte
  alignment,   ALIGNED(1)  specifies  word  alignment,  ALIGNED(2)
  specifies  longword  alignment,  ALIGNED(3)  specifies  quadword
  alignment,  ALIGNED(4) specifies octaword alignment, ALIGNED(9),
  specifies  512-byte   alignment,   and   ALIGNED(13)   specifies
  8192-byte alignment.

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