Comparison Instructions Section 3-7
Description BCMP(068) compares the source data (S) to the 16 ranges defined by pairs
of lower and upper limit values in B through B+31. The first word in each pair
(B+2n) provides the lower limit and the second word (B+2n+1) provides the
upper limit of range n (n = 0 to 15). If S is within any of these ranges (inclusive
of the upper and lower limits), the corresponding bit in R is turned ON. The
rest of the bits in R will be turned OFF.

For example, bit 00 of R is turned ON if S is within the first range (B
≤ S ≤
B+1), bit 01 of R is turned ON if S is within the second range (B+2 ≤ S ≤ B+3),
..., and bit 15 of R is turned ON if S is within the fifteenth range (B+30
≤ S ≤
B+31). All other bits in R are turned OFF.
