Al  DSECTs are assumed by the assembler to be (at least) doubleword aligned.

Not a clue what you are showing here.

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
