This phenomenon, whether or not it is intentional, occurs for byte-aligned/byte-sized data as
well, for example:
DAT
...results in only the low bytes of each value, $AA and $11 being stored in consecutive
locations.
Occasionally, however, it is desirable to store an entire large value as smaller elemental units
that are not necessarily aligned according to the size of the value itself. To do this, specify
the value’s size just before the value itself.
DAT
This example specifies byte-aligned data, but a word-sized value followed by a long-sized
value. The result is that the memory contains $AA and $FF, consecutively, and following it,
$11, $55, $99 and $BB.
If we modify line three of the first example above as follows:
...then we’d end up with $F8, $24, $01, and $00 occupying bytes 12 through 15. Byte 15 is
the upper byte of the value and it just happens to be immediately left of the next long
boundary so no additional zero-padded bytes are needed for the next long-aligned data.
Optionally, the Symbol field of syntax 1 can be included to “name” the data. This makes
