Content of *DM word is not BCD when set for BCD.
ER (A50003):
GR (A50005): Cp1+1 and Cp1 is greater than Cp2+1 and Cp2.
EQ (A50006): Cp1+1 and Cp1 equals Cp2+1 and Cp2.
LE (A50007): Cp1+1 and Cp1 is less than Cp2+1 and Cp2.
When CIO 000000 is ON in the following example, the eight-digit content of
CIO 0011 and CIO 0010 is compared to the eight-digit content of CIO 0009 and
CIO 0008 and the result is output to the GR, EQ, and LE Flags. The results re-
corded in the GR, EQ, and LE Flags are immediately saved to CIO 000200
(Greater Than), CIO 000201 (Equals), and CIO 000202 (Less Than).

When the execution condition is OFF, BCMP(022) is not executed. When the
execution condition is ON, BCMP(022) compares S 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 providing the
upper limit. If S 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.
