Defining Byte Alignment—Example		of	Correct		Coding
The following			example		program shows	a	CHAR(3) bytes reserved field b
to the structure to maintain 4-byte							alignment.16/ on(shownpage		at9-25). This
corresponds		.to14/ on page 9-23 in the					incorrect coding example. The 3
bytes	are	included in the length of the						replace .17/variableon -length		rec
page	9-26	shows		the	variable-length	record		is now 4-byte aligned		(re
16 is divisible by 4). This corresponds.15/ pageto 9-24 in the incorrect										cod
example.
