All data must be in BCD. Press the CONT/# Key before entering a constant
for CD.
N is the rightmost digit of CB and determines the size of the comparison
block; there will be N+1 comparison ranges. BCMP(34) compares CD to the
ranges defined by a block consisting of CB+1, CB+2, ..., CB+(2N+2). Each
range is defined by two words, the first one providing the lower limit and the
second word providing the upper limit, as shown below. If the lower limit is
less than the upper limit, the corresponding bit of the result word, R, will be
turned ON whenever CD is within the preset range.

If the lower limit is greater than the upper limit, the corresponding bit of the
result word will be turned ON whenever CD is not within the preset range.
