If the content of CB or the table data are changed during execution, execu-
tion will continue with the new values.
ER:
Indirectly addressed DM word is non-existent. (Content of

DM word
is not BCD, or the DM area boundary has been exceeded.)
The following example shows the comparisons made and the results pro-
vided for BCMP(34). Here, the comparison is made during each scan when
0000 is ON. The rightmost digit of CB (DR 00) is 5, so the comparison block
is CB+1 to CB+(2N+2) or DR 01 to DR 12.

When the execution condition is OFF, CLC(44) is not executed.When the ex-
ecution condition is ON, CLC(44) turns OFF CY (0312).

When the execution condition is OFF, ADD(40) is not executed. When the
execution condition is ON, ADD(40) adds the contents of Au, Ad, and CY,
and places the result in R. CY will be set if the result is greater than 9999.
