and stores the result in the destination location. The addition is performed using binary-
coded decimal arithmetic. The operands, which are packed binary-coded decimal
numbers, can be addressed in two different ways:
This operation is a byte operation only.
X — Set the same as the carry bit.
N — Undefined.
Z — Cleared if the result is nonzero; unchanged otherwise.
V — Undefined.
C — Set if a decimal carry was generated; cleared otherwise.

Normally, the Z condition code bit is set via programming before
the start of an operation. This allows successful tests for zero
results upon completion of multiple-precision operations.
