represent the device numbers which 
contains the data to be compared 
The  comparison operation instructions make numerical magnitude comparisons (such 
3s 
=, 
>>, 
<< 
etc.) between 
two 
pieces 
of 
data. They are handled 
as 
a 
contact, and turn 
ON when the preceding condition is true. The application of comparison instructions is 
the same as that 
of 
a contact instruction for the corresponding sequence instruction as 
indicated below 
LD, LDI (LD 
=, 
LDD 
=), 
AND, ANI (AND 
=, 
ANDD 
=), 
OR, 
OR1 
(OR 
=, 
ORD 
=) 
There are 
36 
different types 
of 
comparison operation, combined in to 
6 
main groups.
