Chapter 5: Standard RLL Instructions - Logical
And Double (ANDD)
1
The And Double is a 32-bit instruction that
230
logically ANDs the value in the accumulator with
240
two consecutive V-memory locations or an 8-digit
2
250-1
(max.) constant value (Aaaa). The result resides in
the accumulator. Discrete status flags indicate if the
260
3
result of the And Double is zero or a negative
number (the most significant bit is on).

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 and V2001 will be loaded into
the accumulator using the Load Double instruction. The value in the accumulator is anded
10
with 36476A38 using the And Double instruction. The value in the accumulator is output to
V2010 and V2011 using the Out Double instruction.
