Logical Instructions (Accumulator)

And (AND)
The And instruction is a 16-bit instruction that logically ANDs
230
the value in the lower 16 bits of the accumulator with a
240
specified V-memory location (Aaaa). The result resides in the
250-1
accumulator. The discrete status flag indicates if the result of the
260
And is zero.

Discrete Bit Flags
SP63
NOTE: The status flags are only valid until another instruction that uses the same flags is executed.
In the following example, when X1 is on, the value in V2000 will be loaded into the
accumulator using the Load instruction. The value in the accumulator is anded with the value
in V2006 using the And instruction. The value in the lower 16 bits of the accumulator is
output to V2010 using the Out instruction.
