Structured Types Alignment (packed modifier)

By default, the data in a structured type is aligned on double-word boundaries for faster access. However it's possible to include the reserved word packed to enable data compression.
For example,

type
  TEmployee: = packed record
    name: String[80];
    appointment_id: Word;
    stage: Byte;
end;

Starting from TMT Pascal 4, the setting defined by the {$OA} directive can be overridden by specifying the packed reserved word.
