Each lower limit word in the comparison block must be less than or equal to
the upper limit.
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+32. Each range is defined
by two words, the first one providing the lower limit and the second word pro-
viding the upper limit. If CD is found to be within any of these ranges (inclu-
sive 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.

Flags
ER:
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.)
