The following example shows the comparisons made and the results pro-
vided for BCMP(68). Here, the comparison is made during each cycle when
00000 is ON.

When the execution condition is OFF, TCMP(85) is not executed. When the
execution condition is ON, TCMP(85) compares CD to the content of TB,
TB+1, TB+2, ..., and TB+15. If CD is equal to the content of any of these
words, the corresponding bit in R is set, e.g., if the CD equals the content of
TB, bit 00 is turned ON, if it equals that of TB+1, bit 01 is turned ON, etc. The
rest of the bits in R will be turned OFF.
Flags ER: The comparison table (i.e., TB through TB+15) 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.)
