1.2.2 $A1, $A2,$A4 and $A8

These directives are the same as the $PACKRECORDS directive (see section 1.2.60, page 153), but they have the alignment specifier embedded in the directive. Thus the following:

{$A8 }

is equivalent to

{$PACKRECORDS 8}

Note that the special cases of $PACKRECORDS cannot be expressed this way.
