If the input data (S) is greater than or equal to the lower limit (C) and less than or
equal to the upper limit (C+1), 0000 will be output to D and the Equals Flag
(A50006) will turn ON.

If the output data is less than 8000 or greater than 7FFF, the sign will reverse. For
example, if the lower limit is 0100 and the input data is 8000, the output data will
be as follows:
8000 – 0100 = 7F00

Precautions The lower limit (C) must be less than or equal to the upper limit (C+1).
Note Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): The upper limit setting is less than the lower limit.
The content of a*DM word is not BCD when set for BCD.
> (A50005): The input data (S) is greater than the upper limit (C+1).
EQ (A50006): The output data is all zeros.
< (A50007): The input data (S) is less than the lower limit (C).
N (A50008): The output data is a negative number.
Example When CIO 000000 turns ON in the following example, one of the following will
occur:
• If the binary content of CIO 0001 is within the range specified by the content of
D00100 and D00101, 0000 will be output to D00110.
• If the binary content of CIO 0001 is greater than the content of D00101, the
result of (CIO 0001 minus D00101) will be output to D00110.
• If the binary content of CIO 0001 is less than the content of D00100, the result
of (CIO 0001 minus D00100) will be output to D00110.
