For example, bit 00 of R is turned ON if S is within the first range (B
B+1), bit 01 of R is turned ON if S is within the second range (B+2
..., and bit 15 of R is turned ON if S is within the fifteenth range (B+30
B+31). All other bits in R are turned OFF.

Equals Flag =
An error will not occur if the lower limit is greater than the upper limit, but 0
(not within the range) will be output to the corresponding bit of R.
When CIO 0.00 is ON in the following example, BCMP(068) compares the
content of D100 with the 16 ranges defined in D200 to D231 (i.e., D200 and
D201, D202 and D203, etc.) and turns ON the corresponding bits in D300
when S is within the range or OFF when S is not within the range.
