Some of the data manipulation instructions use 32 bits. They use two consecutive V
memory locations or an 8 digit BCD constant to manipulate data in the accumulator.
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 the
accumulator is added with the value in V2006 and V2007 using the Add Double
instruction. The value in the accumulator is copied to V2010 and V2011 using the
Out Double instruction.
