+; Tests MVQA and MVQB.

+; Every ALU result lands in Q, and Q is not an ALU operand. Without these two
+; instructions the only way to use a result in the next sum is to store it into
+; Data Memory and load it back, which costs two instructions and a Data Pointer
+; that has to be pointing somewhere sensible.
+;
+; Correct output is:
+;   AAA
