I think you need to specify the length of the second operand or else it will
take the length of WKPACK and pick up bytes beyond the end of WKPACK

May I suggest not obfuscating the program?
ZAP is a trivial instruction for the job,
and does not need a constant area.

In other words, can one expand the remainder from a DP instruction to
the entire field?
The field can be expanded.
Ensure that the right-most byte of
The second operand must end on or after the end (last byte) of the first
operand for correct results.
