[Coming from Wintel & Delphi world, pardon the intrusion:- ]
Borland's current Pascal compiler, called Delphi, also uses Packed. It
turns off alignment for arrays and record structures of any type. This
is typically used for files or other data structures, whose structure
is outside your control, and which are defined by programs on previous
processors. For example, if you are reading a file whose structure was
defined years ago by a real-mode DOS program, or passing a data
structure to a DLL with such a mindset. "Packed" lives!
