EQ Operand 1 = Operand 2
NE Operand 1  Operand 2
GT Operand 1 > Operand 2

[Example 1] LET 1 10 Assign 10 to variable 1.
CPEQ 1 10 600 Turn ON flag 600 if the content of variable 1
is 10.
600 ADD 2 1 Add 1 to variable 2 if flag 600 is ON.
[Example 2] LET 1 2 Assign 2 to variable 1.
LET 2 10 Assign 10 to variable 2.
LET 3 10 Assign 10 to variable 3.
CPEQ *1 *3 310 Turn ON output 310 if the content of variable
1 (variable 2) is not equal to the content of
variable 3.
