When the execution condition is OFF, BCMP(68) is not executed. When the
execution condition is ON, BCMP(68) compares CD to the ranges defined by a
block consisting of of CB, CB+1, CB+2, ..., CB+31. Each range is defined by two
words, the first one providing the lower limit and the second word providing the
upper limit. If CD is found to be within any of these ranges (inclusive of the upper
and lower limits), the corresponding bit in R is set. The comparisons that are
made and the corresponding bit in R that is set for each true comparison are
shown below. The rest of the bits in R will be turned OFF.

Normally the first word in the range is less than the second, but if the first word in
the range is greater than the second, the corresponding bit in R will be turned
OFF when CD is outside of the range defined by the two words, as shown in the
following diagram.

The comparison block (i.e., CB through CB+31) exceeds the data area.

Indirectly addressed DM word is non-existent. (Content of 

DM word is

not BCD, or the DM area boundary has been exceeded.)
