When CIO 000000 turns ON in the following example, one of the following will
occur:
If the binary content of CIO 0001 is less than zero, the result of CIO 0001 plus
D00100 will be output to D00110.
If the binary content of CIO 0001 is equal to zero, 0000 will be output to
D00110.
If the binary content of CIO 0001 is greater than the content of D00100, the
result of (CIO 0001 plus D00100) will be output to D00110.

When the execution condition is OFF, ANDW(130) is not executed. When the
execution condition is ON, ANDW(130) logically AND's corresponding bits of I
and I and places the result in R.

Refer to page 115 for general precautions on operand data areas.
Content of *DM word is not BCD when set for BCD.
ER (A50003):
EQ (A50006): The result is 0.
N (A50008): Shows the status of bit 15 of R after execution.
When CIO 000000 is ON in the following example, the logical AND is taken of
corresponding bits in CIO 0010 and CIO 0020 and the results is placed in corre-
sponding bits of D00200.
