The above example declares a byte-aligned, byte-sized data table, called
consisting of the following ten values: 64, $AA, $AA, $AA, $AA, $AA, $AA, $AA,
$AA, 55. There were eight occurrences of $AA due to the [8] in the declaration
immediately after it.

A more recommended way to achieve the previous example’s result is to include the
optional Offset field. The previous code could have been written as follows:
