NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the value in V2000 and V2001 will be loaded
into the accumulator using the Load Double instruction. The value in V2006 and V2007 is
subtracted from the value in the accumulator. The value in the accumulator is copied to V2010
and V2011 using the Out Double instruction.

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