NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the value in V1400 and V1401 will be loaded
into the accumulator using the Load Double instruction. The binary value in V1420 and
V1421 is subtracted from the binary value in the accumulator using the Subtract Binary
Double instruction. The value in the accumulator is copied to V1500 and V1501 using the
Out Double instruction.

Subtract Binary Double (SUBBD)
Subtract Binary Double is a 32-bit instruction that subtracts the
binary value (Aaaa), which is either two consecutive V-memory
locations or an 8-digit (max.) binary constant, from the binary
value in the accumulator. The result resides in the accumulator.
